Some people with fibromyalgia perspire heavily and may even believe they have a fever. This is due to what’s called an autonomic dysfunction within the hypothalamus, the almond-sized area in the brain that controls sleep and regulates sweating, bowel movements, and other automatic body functions. “The autonomic dysfunction causes the increase in sweating,” Teitelbaum says. Some medications and lifestyle changes that can keep you cool and dry may help with this fibromyalgia symptom.
Many of these unusual fibromyalgia symptoms respond to general treatment approaches. If not, talk with your doctor about targeted recommendations that may help.
