A significant soreness in the right posterior back is caused by strain in many patients, mainly due to lumbar muscle strain, and lumbar disc herniation. The acute phase of pain can be treated with pain relieving medications, commonly oral aminoglutethimide tablets, or nimesulide dispersible tablets. B vitamins can also be given, which have a nerve-nourishing effect. In addition, if the condition or conditions allow, local physiotherapy can also be chosen, mainly hot compresses, massage or acupuncture, etc., which can relieve the patient’s symptoms of discomfort. For patients with simple lumbar muscle strain, they can also choose to actively exercise the muscles of the lower back, which can also relieve the condition. If lumbar disc herniation is severe enough to cause spinal stenosis, surgery is also an option.
