I m a 45 year old female, in good health. Really enjoy working out. Lately I ve had muscle pain and fatigue very quickly. If I work out, my muscles in my hands and feet get into knots and are very painful. The muscle pain seems to coincide with how much I use them. For example, if I do pull ups or lift weights, my hands and back hurt. If I m standing or running my feet hurt. I have to make sure my bladder is empty or it will also start to cramp up. This is not normal for me. I ve been ignoring it as it has gradually increased. please advise
