Hi I'm 37 diagnosed with fibromyalgia, probable MCTD, hypothyroidism, and was told the purplish rash on my legs (worse on knees) was livedo recularis. I'm being tested for APS but the APS group says there rash looks different. Also it's on my arms but mostly my legs. It's been visible everyday for 3 or more years. On bad days it actually hurts a lot on my knees and turns purple and black but if I apply heat it turns bright red. Anyone recognize my rash?
