A strained muscle in the chest, if it is a less serious muscle strain, can usually recover in 2-3 weeks. If it is a more serious muscle strain, it may take 1-2 months. Muscle strains can generally choose conservative treatment, local can be combined with hot compresses. In addition, ointments that activate blood circulation and resolve blood stasis, such as pain-relieving ointment treatment, and also spraying swelling and pain aerosol can also help recovery. Temporarily avoiding upper limb exertion, chest expansion exercises, and coughing can help relieve the pain of strained chest muscles. For more obvious pain that interferes with normal rest, topical painkillers, such as etofenacin gel or oral painkillers, such as meloxicam tablets, can be applied to help relieve local pain and reduce symptoms.
