Lumbar muscle strain, if the pain is severe, can usually be alleviated using the following methods. First and foremost, during the acute phase, what is primarily needed? First, you need to rest and immobilize, mainly ceasing some activities and ideally lying on a hard bed in a supine position with hips and knees flexed. Secondly, for the painful area, you can apply appropriate physiotherapy. This includes traditional Chinese massage and acupuncture. Thirdly, if there are specific fixed painful points, you might consider blockade therapy. Fourthly, when the pain is particularly severe and affects your work and rest, you can take some non-steroidal anti-inflammatory drugs (NSAIDs). Additionally, use some stimulating medicines or stimulating liniments. If the pain severely impacts your mood and work, you might also consider some sedatives. Fifthly, you can use some external or internal traditional Chinese medicine, which is usually very effective in managing pain.
