Chronic Regional Pain Syndrom (RSD)
Chronic regional pain syndrome, also known as reflex sympathetic dystrophy (RSD) syndrome, involves long-term, intense pain that occurs after an injury and tends to get worse over time instead of getting better. This condition most often affects the arms, legs, hands or feet and can spread to nearby areas as it progresses. In addition to pain, patients may also experience swelling, sweating, skin sensitivity and more.
The cause of RSD is not specifically known, although it is often linked to the sympathetic nervous system prolonging pain or an abnormal immune system response that prevents proper healing.
While there is no cure for this condition, there are several treatment options to relieve symptoms, including analgesics, antidepressants, corticosteroids and opioids. Alternative treatment methods may include physical therapy, sympathetic nerve block, and spinal cord stimulation. Patients may be prescribed a combination of these treatments in order to achieve effective pain relief.
