Inflammation Pain and
Tissue injury Tissue injury arising from ongoing exposure to high-intensity stimului leads to a pain sensation continuing beyond the removal of the originating stimulus. The systems underlying this spinal facilitation include: Spinobulbospinal pathway Afferent input activates caudal midline raphe-spinal serotonergic neurons which terminate in dorsal horn neurons to facilitate the activity in deep dorsal horn projection systems [ 7 - 8 ]. Loss of local inhibition Local dorsal horn neuronal excitability is under the tonic control of local inhibitory GABAergic and glycinergic interneurons.
Local non neuronal cell systems Peripheral inflammation leads to both acute and chronic indices of activation of spinal microglia and astrocytes. Migration of non-neuronal inflammatory cells into the DRG Peripheral inflammation results in the appearance of macrophages in the DRG, but not the spinal cord [ 12 ]. Peripheral nerve injury Injury to the peripheral nerve leads to a pain state with persistency and components of hyperalgesia and allodynia aversive sensation generated by an otherwise innocuous stimulus referred to the distribution of the injured nerve.
The peripheral and spinal mechanisms underlying this increased spontaneous activity are broadly summarized in terms of: Migration of nonneuronal inflammatory cells into the DRG After nerve injury, increased macrophages and neutrophils have been shown in the DRG [ 24 - 25 ].
Activity-induced facilitation The ongoing afferent traffic is believed to contribute importantly to the initiation of a central sensitization state with several components including activation of the NMAD receptors and increased AMPA subunit expression [ 26 - 27 ]. Spinobulbospinal facilitatory pathways As noted above, spinobulbospinal pathways lead to the activation through the caudal midline raphe of serotonergic projections, which terminate in dorsal horn neurons to activate dorsal horn projection systems.
Activation of non-neuronal cells After nerve injury there are trophic changes in the appearance of microglia and astrocytes, suggesting increased activity of non-neuronal cells [ 11 ].
Migration of non-neuronal inflammatory cells into dorsal horn Peripheral nerve injury produces segmentally organized disruption of the blood brain barrier [ 33 ] and the influx of T cells and macrophages [ 34 ]. Separation of tissue vs. Pharmacology As show in table 1 , in preclinical models, inflammatory hyperalgesia are frequently sensitive to agents such as NSAIDs and opiates whereas neuropathic pain states are not.
Table 1 Analgesic pharmacology of nerve and tissue injury pain states. Open in a separate window. Comparison of tissue vs. Mechanims mediating persistent pain following tissue injury or nerve injury Following tissue injury or nerve injury, pathological changes that might lead to persistent pain in the DRG 1 and the spinal cord dorsal horn 2. Voltage-gated sodium channels VGSCs control the propagation of nerve impulses and are therefore essential for the excitability of neurons.
Voltage-gated calcium channels VGCCs are critical in controlling neurotransmitter release. Post synaptic activation Release of glutamate in the spinal dorsal horn leads to activation of a variety of ionotrophic receptors. Disinhibition Dorsal horn nociceptive neurons are under powerful inhibitory control.
Involvement of spinal glia It is increasingly recognized that glias, especially microglias play important roles in the generation of chronic pain [ 90 - 92 ]. Conclusion There is no doubt that inflammatory pain and neuropathic pain share common mechanisms, although the time course and relative contribution of each of these mechanisms might be different.
Inflammatory pain and neuropathic pain can be distinguished from the following characteristics: Mechanisms common to both inflammatory and neuropathic pain include altered expression of cytokines, cytokine receptors and VGSCs in the DRG, enhanced glutamate release and receptor functions, disinhibition and glia activation and invasion in the spinal dorsal horn.
Nerve injury marker ATF3 is observed in the DRG neurons following prolonged peripheral inflammation, suggesting the pain of inflammatory origin may evolve into a condition that resembles neuropathic pain. Footnotes This is a PDF file of an unedited manuscript that has been accepted for publication.

Allodynia is defined as pain resulting from a stimulus that ordinarily does not elicit a painful response e. Hyperalgesia is defined as an increased sensitivity to normally painful stimuli. Examples of neuropathic pain include carpal tunnel syndrome, trigeminal neuralgia, post herpetic neuralgia, phantom limb pain, complex regional pain syndromes and the various peripheral neuropathies. Interestingly, ED, TNF-alpha- and InterLeukinpositive cells increased more markedly in allodynic rats than in non-allodynic ones.
The magnitude of the inflammatory response was not related to the extent of damage to the nerve fibers because rats with complete transection of the nerves displayed much lower production of inflammatory cytokines than rats with partial transection of the nerve This is a finding commonly observed in patients where a minor injury results in severe pain that is out of proportion to the injury.
In another study, animals exhibiting heat hyperalgesia as a sign of neuropathic pain seven days after loose ligation of the sciatic nerve exhibited a significant increase in the concentration of brain derived neurotrophic factor BDNF in their lumbar spinal dorsal horn. In clinical trials with nerve growth factor for the treatment of Alzheimer disease and peripheral neuropathy, induction of pain has been the major adverse event In one study, the use of trkA-IgG, an inhibitor of Nerve Growth Factor NGF reduced neuroma formation and neuropathic pain in rats with peripheral nerve injury 35 In another study, the systemic administration of anti-nerve growth factor NGF antibodies significantly reduced the severity of autotomy self mutilating behavior induced by nerve damage and prevented the spread of collateral sprouting from the saphenous nerve into the sciatic innervation territory It is most often initiated by trauma to a nerve, neural plexus, or soft tissue.
Diagnostic criteria are the presence of regional pain and other sensory changes following a painful injury.
The pain is associated with changes in skin color, skin temperature, abnormal sweating, tissue swelling. With time, tissue atrophy may occur as well as involuntary movements, muscle spasms, or pseudoparalysis The inflammatory mediators that are generated especially IL-6 accelerate the rate at which bone is broken down.
The bone loss is further aggravated by decreased use of the affected body part due to pain. Recent research and studies including various clinical and experimental investigations prove that Sudeck started on the right path We now have a better understanding of the complexity of the inflammatory response, and we believe that inflammation and the inflammatory response do not just provoke the signs and symptoms of sympathetic hyperactivity.
Soft tissue or nerve injury causes release of the inflammatory mediators and excitation of sensory nerve fibers. Reverse antidromic firing of these sensory nerves causes release of the inflammatory neuropeptides at the peripheral endings of these fibers. These neuropeptides may induce vasodilation, increase vascular permeability, attract other immune cells such as T helper cells and excite surrounding sensory nerve fibers -- a phenomenon referred to as neurogenic inflammation.
At the level of the central nervous system, the increased input from peripheral pain receptors alters the central processing mechanisms. Activity in sympathetic fibers is associated with excessive sweating, temperature instability of the extremities and can induce further activity in sensitized pain receptors and, therefore, enhance pain and allodynia sympathetically maintained pain.
This pathologic interaction acts via noradrenaline released from sympathetic terminals and newly expressed receptors on the afferent neuron membrane Perpetuation of the sympathetic response has been proposed be related to central dysregulation of nociceptive impulses.
This dysregulation may be mediated by wide dynamic range neurons in the spinal cord Populations of C fibers contain peptides such as substance P sP and calcitonin gene-related peptide CGRP , as well as amino acids such as glutamate. In situ hybridization shows labeling for NK-1 and NMDA receptor units in the dorsal gray matter, particularly in the substantia gelatinosa where small afferents are known to terminate.
Prolonged ischemia from the sympathetic vasoconstriction produces more pain, establishing a reflex arc that promotes further sympathetic discharge and vasospasm. This is compounded by the local response to trauma, with liberation of substantial amounts of proinflammatory mediators, such as histamine, serotonin, and bradykinin.
The result is a swollen, painful, stiff, nonfunctioning extremity. Local tissue inflammation can also result in pain hypersensitivity in neighboring uninjured tissue secondary hyperalgesia by spread and diffusion of the excess inflammatory mediators that have been produced as well as by an increase in nerve excitability in the spinal cord central sensitization.
This can result in a syndrome comprising diffuse muscle pain and spasm, joint pain, fever, lethargy and anorexia. The results of several experimental studies suggest that sympathetic dysfunction may also consist of super sensitivity to catecholamines induced by nerve injury autonomic denervation Part of this occurs due to injured sensory nerves and immune cells developing receptors for the chemical transmitter norepinephrine and epinephrine catecholamines , which are normally released by sympathetic nerves and also circulate in the blood.
Stimulation of these receptors by locally released or circulating catecholamines produces sympathetic effects such as sweating, excessive hair growth and narrowing of blood vessels In addition and under certain conditions, catecholamines may boost regional immune responses, through increased release of Interleukin-1, tumor necrosis factor-alpha, and Interleukin-8 production. The levels of bradykinin were four times as high as the controls.
A few showed increased levels of the other inflammatory chemical mediators Inflammation of the bursa is known as bursitis. A bursa is a small sac containing fluid that lies between bone and other moving structures such as muscles, skin or tendons. The bursa allows smooth gliding between these structures. A bursa allows a tendon or muscle to move smoothly over a bone by acting as an anti-friction device and shielding the structures from rubbing against bones. Bursae are found in the knee, elbow, shoulder and wrist.
If the tendons become thickened and bumpy from excessive use, the bursa is subjected to increased friction and may become inflamed. Tendonitis is inflammation or irritation of a tendon. Tendons are the thick fibrous cords that attach muscles to bone. They function to transmit the power generated by a muscle contraction to move a bone. Since both tendons and bursae are located near joints, inflammation in these soft tissues will often be perceived by patients as joint pain and mistaken for arthritis.
Symptoms of bursitis and tendonitis are similar: Pain may be prominent at night. Almost any tendon or bursa in the body can be affected, but those located around a joint are affected most often. The most common cause of tendonitis and bursitis is injury or overuse during work or play, particularly if the patient is poorly conditioned, has bad posture, or uses the affected limb in an awkward position.
Occasionally an infection within the bursa or tendon sheath will be responsible for the inflammation. Tendonitis or bursitis may be associated with diseases such as rheumatoid arthritis, gout, psoriatic arthritis, thyroid disease and diabetes. In one study of thirty-nine patients with rotator cuff diseases, the levels of the cytokine Interleukin-1 beta was significantly correlated with the degree of pain.
The combined results of immunohistochemistry indicate that both synovial lining and sublining cells produce IL-1beta, while synovial lining cells predominantly produce the anti-inflammatory intracellular InterLeukin-1 receptor antagonist icIL-1ra and sublining cells secrete InterLeukin-1 receptor antagonist sIL-1ra In one study, the levels of interleukin-1 beta were significantly higher in the shoulder joints in patients with anterior instability and chronic inflammation of the joint In another study, immunohistological staining demonstrated the expression of Interleukin-1 beta Interleukin-1 beta , Tumor necrosis factor alpha TNF-alpha , transforming growth factor beta TGF-beta , and basic fibroblast growth factor bFGF in subacromial bursa derived from the patients suffering from rotator cuff tear IL-6, in turn, can induce release of corticotrophin-releasing factor 50 51 , which results in elevated systemic levels of corticosteroids.
Vulvar vestibulitis syndrome is a major subtype of vulvodynia. It is a constellation of symptoms and findings involving and limited to the vulvar vestibule that consists of: The syndrome has been seen in association with subclinical human papillomavirus, chronic recurrent candidiasis, chronic recurrent bacterial vaginosis, chronic alteration of vaginal pH, and the use of chemical and destructive therapeutic agents In a study of VVS cases and asymptomatic controls, median tissue levels of inflammatory cytokines: IL-1 b and TNF-a, from selected regions of the vulva,, vestibule, and vagina were 2.
Analysis revealed a significant 2. The study authors concluded that inflammatory cytokine elevation may contribute to the pathophysiology of mucocutaneous hyperalgesia In accordance with our Law of Pain, the origin of all pain is inflammation and the inflammatory response.
Treatment of pain syndromes should be based on these principles:. Pain Clinic, we have successfully treated a variety of pain syndromes by utilizing these principles.
This unifying theory of the biochemical origin of pain is compatible with, inclusive of, and unifies existing theories and knowledge of the mechanism of pain including the gate control theory, and theories of pre-emptive analgesia, windup and central sensitization. Our current knowledge is rudimentary and but a beachhead in the vast frontier of inflammation and the inflammatory response.
We have medications for only a few of these mediators. More research is needed to understand and develop new drugs and interventions to treat inflammation and the inflammatory response and thus to conquer pain.

8 Food Ingredients That Can Cause Inflammation
Chronic, subtle, systemic inflammation is a possible factor in stubborn musculoskeletal pain. It can have many underlying causes, from bad. People will feel pain, stiffness, discomfort, distress, and even agony, depending on the severity of the inflammation. Inflammatory arthritis is the term used to describe conditions characterized by pain, swelling, tenderness and warmth in the joints, as well as morning stiffness.
