What is the best thing to do when you get back from the gym and can't move your arms?
Take a mild pain reliever such as Tylenol. Apply a heating pad to your arms. And be careful not to overwork your muscles the next time you go to the gym.
Get someone to move them for you.
Ice never hurts.
Ice hot cream
Muscle relaxer like aleve and heat. Heat for muscle, ice for joints.
