Referred to as a medical syndrome, Reflex sympathetic dystrophy (RSD) is characterised by pain, swelling, and extreme vasomotor dysfunction. Its cause is usually unknown but is considered a result of trauma or surgery. Immobility of the limbs may cause RSD. An individual after suffering a stroke may develop RSD in the upper limb and this is usually called as shoulder-hand syndrome. One may also develop this condition in the absence of a particular impulsive event. Studies categorises RSD as type 1 complex regional pain syndrome (CRPS), and usually occurs due to a nerve injury.
At present, medical professionals offer various treatments to relief patients suffering from RSD. Sympathetic blockade and anti-inflammatory therapy are two major approached used in the treatment of patients with this condition. Doctors recommend surgical sympathectomy to patients with refractory Reflex sympathetic dystrophy (RSD) that has shown response to sympathetic blockade earlier. Another surgical option for patients with this condition is spinal cord stimulation. Another condition that affects your nerve fibers and skin is the Postherpetic neuralgia. It is a problem of shingles caused by the virus of chickenpox (herpes zoster).
Usually, a person get relieved of shingles complications within a few weeks, but if one suffers from pain even after rashes and blisters have disappeared then it is postherpetic neuralgia. It also causes severe pain that may further impede your sleep and appetite. Elderly people are more at risk to get affected with this condition. Though medical science fails to offer cure for this condition, it has many treatment options easing symptoms. Some of the common symptoms include:
- Pain: It is commonly described as burning, sharp and poking, and aching.
- Itching and insensitivity: It causes a feeling of itching or deadness making the affected are insensitive.
- Weakness or paralysis: One may also suffer from muscle weakness or paralysis; however, it happens in rare cases.
