CRPS (Complex Regional Pain Syndrome) , also known as RSD (Reflex Sympathetic Dystrophy) is a very unique medical condition that involves extreme pain in the affected limb as well as associated symptoms , including skin discoloration, redness, skin turning purple, hair growth, changes to the fingernails or toenails.
It is rare but it is extremely painful. As an attorney experienced in handling Complex Regional Pain Syndrome (RSD) cases what I have been able to do is subjectively document the symptoms for the patient over time. While their physician may note the changes, it is important to objectively document it through photographs and through temperature changes you have to document using an accurate temperature reader. These can be incorporated into the medical notes, so later on their is no dispute about these objectives.
