Pour some Epsom salt in a hot bath and just lay and relax in there. The Epsom salt and heat should help your muscles relax. If you have anyone that would be willing to rub on your pain areas I would ask them to rub on you after your bath when the muscles are relaxed a bit. If you don't have anyone and you are on your own, get a tennis or ratchet ball, put it on the floor, lay on top of it with your back on the ball, move around on top of it until you find where it is hurting, once you find the painful area, stop moving around and just lay your back on top of the ball and leave it in that one spot for a little while. This should make the muscle relax and give out releasing the tension. Good Luck!
