Hi, I am experiencing severe muscle pain two days after a fairly benign workout (about 10 minutes of lunges and squats using just bodyweight). I ve worked out much harder in the past, with heavy weights and not experienced anything like this. I can hardly walk, sit, or stand. My quads are even painful to the touch. Coincidentally, I have also developed a bumpy reddish rash on one side of my neck and later inside the opposite wrist. Cannot think of any new food or contact that might be causing it. Thanks
