Can it cause problems with sweating or temperature regulation

The simple answer is yes! With Fibromyalgia you are dealing with the central nervous system and all its regulatory functions. When this system of the body gets “out of balance” it can cause many overlapping symptoms that seem weird and unrelated to each other. The best thing to do is try to say out of direct sunlight on hot days and try to keep your body warm on cold days. The idea is to give yourself permission to feel as comfortable as possible.
