I Have Been On Mobic For Arthritis From My MD

I have been on Mobic for arthritis from my MD for three years. This past week I asked my doctor about Diclofenac and she placed me on it to see if I get any better pain relieve from it. I looked at the side effects from Mobic to Diclofenac and the first one list was deadly heart and blood vessel side effects like heart attack and stroke. I want to go back to Mobic. I have thumb and finger arthritis and severe degenerative feet arthritis as well. I have never used this site. How can it be free? Thank you. ;-)
