COMPLEX REGIONAL PAIN SYNDROME - Reflex sympathetic dystrophy syndrome (RSD) is a disorder that causes lasting pain, usually in an arm or leg, and it shows up after an injury, stroke, or even heart attack. But the severity of pain is typically worse than the original injury itself. The term reflex sympathetic dystrophy syndrome is actually not a name that doctors use anymore. It’s an older term used to describe one form of Complex Regional Pain Syndrome (CRPS). RSD is sometimes called Type I CRPS, and it’s caused by injury to tissue with no related nerve damage.
When you get hurt, your sympathetic nervous system tells your bloodvessels to get smaller so you don’t lose too much blood at your injury site. Later, it tells them to open back up so blood can get to damaged tissue and repair it.
When you have RSD, your sympathetic nervous system gets mixed signals. It turns on after an injury, but doesn’t turn back off. This causes a lot of pain and swelling at your injury site.
