The most common clinical cause of right lumbar pain is lumbar muscle strain or lumbar muscle spasm, mainly due to prolonged sedentary or bending heavy physical labor, resulting in right lumbar back muscle strain, inflammation of the fascia, and then pain. Because of the local edema and inflammatory reaction of the muscle, sometimes muscle spasm pain may occur. For this condition, first of all, we should remove the cause, avoid prolonged sedentary or bending heavy physical labor, and at the same time, we should strengthen the functional exercise of the lumbar back muscle. If the pain is severe, it can be treated with local massage or hot compresses to relieve muscle spasm and relax the muscles to relieve the pain. At the same time, you can also apply topical Furtalin ointment or apply blood circulation and pain relief cream, and take oral non-steroidal anti-inflammatory and analgesic drugs or muscle relaxation drugs when the pain is severe.
