For the past couple of weeks I have been experiencing severe leg pain from mid buttock to lower calves in both legs. My thighs are sore to the touch and on occasion I am almost unable to move one of my legs while lying in bed because the pain is so severe. Advil relieves the pain to some degree, but not entirely. I have not exercised due to recent hernia surgery and am not taking any medications that are new. I have started Adcirca for PAH in the last 3 days, but that post dates the onset of leg pain. This seems unrelated to skeletal issues as the pain seems to be in the soft tissue. Both legs are affected equally. There is no swelling, numbness, redness, heat or any visible sign of problems. I am mystified. I am a 66 year old female that is active (living on a ranch).
