Cramps in the back muscles are usually caused by overexertion, back muscle strain, local cold, etc., resulting in spasm and pain in the back muscles. Patients can take oral or topical non-steroidal anti-inflammatory drugs for treatment, such as oral loxoprofen sodium extended-release tablets, celecoxib capsules and other drugs, as well as topical flurbiprofen gel paste, futalin ointment, etc., and can be combined with local hot compresses, massage, acupuncture, moxibustion and other physical therapy to relieve symptoms. After the above conservative treatment, patients with mild symptoms can be relieved soon, and patients with more serious symptoms can be relieved significantly in about 1-2 weeks after the above treatment. If there is no obvious relief of symptoms, or if there is persistent aggravation, it is recommended to go to the orthopedic department of the regular hospital in time to improve the relevant examination and clear diagnosis and treatment.
