Oh my! I feel your pain! A few years ago our youngest daughter and her husband got a Wii and I spent Christmas evening boxing with my 8 year old grandson who thought beating the heck out of Meme was great! lol Needless to say, the next morning, I couldn't move! Have you ever taken Motrin or Aleve for pain? If you can take that, they are anti inflammatory meds and it is the inflammation of the muscles that you haven't used in a while that are giving you the problem. Why don't you give your doc a ring and see what he suggests or if he thinks one of the meds I mentioned might be helpful. Good luck. Up North is right, gentle exercise tomorrow is important, those muscles will just tense up again if you don't continue to work them. Even just gentle walking will increase the blood flow and will help the soreness just by warming up the muscles again.
