Muscle spasms in the feet are a type of sudden, intense muscle contractions that can cause sharp pain and limited mobility. They can be caused by overuse or injury, poor posture and movement habits, and underlying medical conditions like diabetes and stroke. Symptoms include sharp pain, muscle cramps, and twisting sensations, which can radiate to other parts of the body. Treatment options include stretching exercises, relaxation techniques, medications, and physical therapy, among others. Proper diagnosis and treatment can effectively manage muscle spasms in the feet.
