Ive seen a chiropractor and he diagnosed locked joint and muscle spasm in my back. what medication can i use for the pain/spasms as it is affecting my mobility,?

Back pain and spasm: One of the best things for muscle spasm and pain is the application of ice directly on the muscle group for 20 min periods and repeat every 1-2 hours if needed. It reduces the inflammation and spasm. Over the counter meds that address this are ibuprofen, aleve and now topical Voltaren gel which works well if applied 4 times a day - about an inch of gel with each application.
