Some cramps are caused by misuse of your muscles. This usually happens while you're exercising. Cramps can also be caused by muscle injury and dehydration. The excessive loss of fluids in the body is referred to as dehydration. Muscle injuries occur when a muscle is strained or torn. They can also happen when a small bone in the muscle breaks. These injuries need to be treated by a doctor. Exercise-related cramping is more common among new exercisers. This is because it takes time before your body gets used to the stresses of training and competing. At first, you will likely suffer from some muscle soreness after each workout. This is normal. As you continue with your workouts, they will become easier and less painful. For most people, cramping affects only one muscle group at a time. You may experience leg cramps due to lack of water intake, fatigue, certain medical conditions, or taking drugs. These can be reduced by changing your posture, wearing comfortable shoes, getting enough sleep, and controlling your diet. If these measures fail, see your physician for advice. Muscle cramping is very painful and should not be ignored. It is important to identify the cause of the cramp and take appropriate action.
