After a hard workout I seem to have a locked up muscle in my calf. When I stand up I can not put my heel to the floor. It is extremely painful, just as if I had a catch in the muscle. I probably worked out too hard, as I am not in shape, but I did work with a trainer who kept a close watchful eye on me. I don't think it is pulled or injured, but it does feel tensed up like it can not release. It is sort of like the restricted movement a crick in the neck causes, only in the calf muscle. What can I do to release it? I've tried stretched (extremely painful!), walking (even more painful as I have a cast on my right foot, still recovering from a severe break and surgery), tried massaging it but the muscle is very sore to the touch. I have a hot pack on it right now and the pharmacist at walgreens recommend some kind of OTC med that I am trying. Any advice to release it?
