for 2-3 mos. I have burning on right side -right foot-relieved w/Aspercreme--also burning both legs where legs join the buttocks--only occurs after sitting for a prolonged period -relieved by laying down on side , taking Tylenol & anelgesic rub applied to the area. I have been diagnosed with Fibromyalgia but these symptoms have only occured in the last 3 months. Could this be related?
