I don't get it over the counter. I go to the doctor and i get a perscription and use my benefits to pay for it.. I believe one time when i didn't have benefits the bottle of.. maybe lets say 20 or 30 tablets (don't quote me on the # of pills) was about 40$
if the pain is that bad and you want to get rid of it.. speak to your doctor and if your doc feels that its right for you get a perscription.
