Generally, patients with lumbar sprain will suffer mainly from lumbar pain, which may affect the normal activities of the waist in serious cases. For example, patients dare not bend or turn around, which is a common clinical symptom of lumbar sprain. First, it is necessary to take an ordinary X-ray film in order to exclude the possibility of fracture and determine an active treatment plan. For patients with lumbar sprain, it is necessary to choose active conservative treatment, such as externally applied plaster to promote blood circulation and remove blood stasis, wearing a waist band to protect the lumbar spine, trying to sleep on a hard bed, and if necessary, take some pain relief drugs orally, such as Nimesulide capsules, to alleviate the patient's pain symptoms, but the drugs need to be taken under the guidance of the doctor.
