<s>[INST] 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 [/INST] Hello, As per what I feel the muscle pain is due to DOES, which is called the delayed onset of muscle soreness. Which is common most times when one has done an exercise after a long time. This particular DOES takes 2-3 days of time to wean off as it's a soreness in the fibers of the muscle.  You can do hot water fermentation and the pain will come down little which will help you perform ADL.  Rest assured DOES don't last more than 2-3 days. Continue exercise but at a slow pace. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.  </s>
