Can anxiety cause back spasms? and if so how can i stop the onset of the spasms or treat them once they've begun? they can last up to 48hrs :(

Valium: In the short run Vailum can help with skeletal muscle spasm and anxiety. Valium is addicting and can cause depression. Physical therapy, massage therapy, other agents ( including applied heat and cold) can help. Evaluation by a chiropractor or physical therapist or physician is usually warranted to diagnosis and manage chronic back problems.
