For some reason I developed spastixity in the last couple of months and haven't been able to get into a doctor. Other than that have been healthy. I researched all over the Web and could not find any otc drugs to help that I could by in store and muscle relaxers require rx. I walked into CVS and found this. Although it relieved my spasms within minutes, the pain persisted and seemed stronger, maybe due to not being able to release in a spasm. I will try it longer and maybe combine some ibuprofen. Thanks for this great medicine!
