A muscle spasm is a sudden tightening of the muscle you can’t control. This may be caused by strain, overworking the muscle, or injury. It can also be caused by dehydration, electrolyte imbalance, diabetes, alcohol use, and certain medicines. If it goes on long enough the muscle spasm causes pain. Common areas for muscle spasm are the legs, neck, and back.
Heat, massage, and stretching will help relax muscle spasm.
When the spasm is in your arm or leg, stretch the muscle passively. To do this, have someone bend or straighten the joint above or below the muscle until you feel the stretch on the sore muscle. You can stretch the muscle actively by moving the affected body part. This will stretch the muscle that is in spasm. For example, if the spasm is in your calf, bend the ankle so your toes point upward toward your knee. This will stretch your calf muscle.
You may use over-the-counter pain medicine to control pain, unless another medicine was prescribed. If you have chronic liver or kidney disease or ever had a stomach ulcer or gastrointestinal bleeding, talk with your healthcare provider before using these medicines.
Follow up with your healthcare provider, or as advised.
