With resolution of the herpes zoster eruption, pain that continues for three months or more is defined as postherpetic neuralgia. Pain is variable, from discomfort to very severe, and may be described as burning, stabbing, or gnawing. Signs: [citation needed] Area of previous herpes zoster may show evidence of cutaneous scarring.
[2] 3-Chlorobenzonitrile can also be produced by dehydration of the aldoxime of 3-chlorobenzaldehyde. [3] It can also be produced by heating 3-chlorobenzylamine and iodine in ammonium acetate aqueous solution. [4] In the presence of copper nanoparticles, 3-chlorobenzonitrile can be reduced by sodium borohydride to 3-chlorobenzylamine. [5]
3-Bromobenzaldehyde is an isomer of bromobenzaldehyde. It is a colorless viscous liquid. It is a colorless viscous liquid. 3-Bromobenzaldehyde can be prepared from 3-nitrobenzaldehyde .
[3] [4] Chronic pain is considered a syndrome because of the associated symptoms that develop in those experiencing this disorder. [5] Chronic pain affects approximately 20% of people worldwide and accounts for 15–20% of visits to a physician. [3] Pain can be categorized according to its location, cause, or the anatomical system which it affects.
Nociplastic pain is a longterm complex pain, one of three mechanisms of pain, defined by the International Association for the Study of Pain as "pain that arises from altered nociception despite no clear evidence of actual or threatened tissue damage causing the activation of peripheral nociceptors or evidence for disease or lesion of the somatosensory system causing the pain". [2]
Complex regional pain syndrome is a multifactorial disorder with clinical features of neurogenic inflammation (inflammation mediated by nerve cells), nociceptive sensitisation (which causes extreme sensitivity or allodynia), vasomotor dysfunction (blood flow problems which cause swelling and discolouration) and maladaptive neuroplasticity ...
