It is possible that you have Gottron's sign, rash from your description. You could look at some images online and see if it looks like what you are experiencing. It is associated with polymyositis or dermatomyositis, an inflammatory autoimmune disorder. Sometimes the skin symptoms precede any other symptoms related to the muscles by months or even years. If you have a purplish discoloration around your eyelids, It is associated, as well as muscle aches pains or weakness. If you want to see a Dr. to check this out, I suggest you go equipped with pictures of your purple knuckles, purplish eyelids if that it present, since these signs come and go. Also a good knowledge of your family medical history and a list of any abnormal symptoms you feel. A rheumatologist is the specialist to see but your PCP could do some preliminary blood tests like CK, sed rate, CRP, ANA and anti-JO antibodies.
