If you mean arthritis I am having good success with Glucosamine and Condroitin - - stops most of the arthritis throbbing type pain.
I know, I am taking this for more then 2,5 years now and it is working.
a few months ago, I could'nt lift my arm and when i finally went to see my doctor, he prescribed me Diclofenac Natrium. It was like a miracle: the pain vanished overal (except for my headache) and i could move freely.
But, after the echo and rontgen which did show 'degenerative wear' (here called arthrose - arthritis is the same with chronic inflammatory as I understood), he told me to stop with the medication for Diclofenac ain't good for long time use. Now the pain is back - so i have to go to the doctor again and plee for more....
