Lumbar muscle strain is mainly caused by long-term poor posture and chronic injuries. Patients with lumbar muscle strain can experience symptoms such as back pain and limited mobility. For the treatment of lumbar muscle strain, it is important to rest and develop good habits of using the back during work. Symptomatic medication treatment can also be applied, such as using non-steroidal anti-inflammatory and analgesic drugs to relieve pain. These drugs can be used for a short period after meals and are effective in alleviating pain. Additionally, treatments like hot compresses, massage, physical therapy, acupuncture, or local blockages can also be used to effectively relieve pain.
