Has anyone had any luck using Ketoprofen? The doctor prescribed it to me for my knee but I havent had any luck using it. It's supposed to be a topical NSAID and I was told that I can use it for my back as well.Also, I'm supposed to be going in for facet joint denervation in a few days, has anyone had any success with it? Any complications? I was told that my PM dr will try this and I will keep a pain diary for 24 hours to see if it helps and if it does then they can try something that lasts for 6 months but he didnt say what that was. Any ideas?
