Cold: cold water or cold air stimulation leads to muscle contracture, which can be relieved by warmth, massage, adding clothing and so on. 2. Local ischemia: external factors such as trauma, impact or long-term local compression lead to local blood supply disorders and muscle spasms, which can be relieved by improving the cause of the disease. 3. Calcium deficiency: insufficient intake of calcium can also lead to muscle contracture, which can be relieved after calcium supplementation. 4. Muscle strain: prolonged exposure to a posture or repeated repetition of the same action, resulting in soft tissue damage, local inflammation, can be relieved by changing the posture, hot compresses, massage and other ways. Muscle spasms at the ribs may also have other causes, it is recommended to go to the hospital, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment.
