Not all people with RSD have all of these symptoms, and not all symptoms necessarily appear at the same time.

Characterized by constant, spontaneous, severe burning pain, known as causalgia.

Usually associated with

• Abnormally acute sensitivity to stimulus (such as touch, hot, cold).
• Diminished sensitivity to stimulus (yes you can have it both ways).
• Distress from painful stimulus (everybody has distress from pain, even if you don't have RSD, other people just have the distress for a lot shorter time!)
• Alterations in blood flow, sweating, edema.
• Pain from hot or cold.
• Pain from mechanical stimulation.
• Muscle weakness.
• Tremors.
• Joint stiffness.
• Anxiety.
• Hopelessness.
• Depression.
• Muscle atrophy.
• Osteopenia.
• Arthropathy.
• Glossy skin.
• Brittle nails.
• Altered hair growth - often thicker hair on the affected extremity.

RSD can also prolong the normal sympathetic response to an injury, such as stubbing a toe or getting a paper cut.
