4. Changes in skin color
Another contrast between the skin of the affected area and the skin on the rest of the body is found with the skin color of a person. The skin at the affected limb, limbs, or farther-flung reaches of the body may often appear either blotchy looking, purple in color, blank and pale, or flushed and red.
A huge variety of skin color fluctuations are possible, and they all have their roots in the same place, with CRPS. One person with CRPS described their left arm as looking like a bowl of Neapolitan ice cream. They described how their hand appeared bright red in color, almost glowing, whilst their forearms up to the elbow looked pale and cold with the upper arm looking the most like their usual skin color, a light brown.
Unfortunately for this person, their arm wasn’t showing signs of strawberry, vanilla, and chocolate flavoring, but just another symptom of CRPS.
