Muscle spasms, also known as muscle cramps, are involuntary and painful contractions that may be alleviated by stretching the muscle. Muscle spasms can be caused by a variety of reasons including muscle fatigue, heavy exercises, pregnancy, dehydration, reduced levels of magnesium and calcium in the body, medications, and hypothyroidism. Physical therapy can help by providing a thorough evaluation and a treatment program which may include exercises to help strengthen and stretch the area, manual therapy to help release tight structures and education for posture and/or diet tips if applicable.
