Symptoms: The main symptoms of lumbar muscle strain are muscle soreness and distension, and the symptoms of pain will be aggravated when the muscles are exerted, and the discomfort will be reduced after proper rest. Fasciitis symptoms are mainly manifested as localized pain, muscle tension or spasm, the symptoms of pain will be aggravated after getting cold, and the symptoms of pain will be reduced after activities. 3.
