I was on hydroxy chloroquine after two other drugs failed as well. It seems the only thing that works for me is 8 mlg of medrol "methylprednisolone" or 10 mlg Prednisone, personally the medrol works the best. Wheni start to decrease my pain starts to increase within a day or two. I have been on this roller coaster for 15 months. I have scoured every health food and supplement stores and online with no real results. The only thing that works on me is the steroids.
