can rsd cause knee issues
As a result, the patient may have RSD due to a knee injury or injury to the foot or hand and yet may develop stimulation and abnormal function of the sympathetic system causing constriction of the blood vessels to the brain.
What is Reflex Sympathetic Dystrophy (RSD) Syndrome? RSD is an older term used to describe one form of Complex Regional Pain Syndrome (CRPS). Both RSD and CRPS are chronic conditions characterized by severe burning pain, most often affecting one of the extremities (arms, legs, hands, or feet). There are often pathological changes in bone and skin, excessive sweating, tissue swelling and extreme sensitivity to touch, known as allodynia.
