After an injury, muscles may spasm, become strained, or even tear. Muscle spasms are tight muscles that usually occur early after an injury. Muscle strains, also called pulled muscles, occur when a muscle or tendon that attaches it to the bone is overstretched or torn. Muscle strains may occur because of improper stretching, lack of warm up, too weak or previously injured and has not had adequate time to recover. At Goodell Physical Therapy a thorough evaluation is performed, exercise and patient education is emphasized to help you recover from and prevent further injury.
