ovarian cancer & R. Arthritis

Hi, I'm a new cancer survivor, my last chemo yesterday. One of my 'now what's' is what kind of arthritis treatment do I return to now. I've taken nothing except prednisone for joint pain during my chemo. But previously I was taking some pretty powerful immune suppresant drugs. It seems like now I should be wanting to encourage my immune system but I do need to control the arthritis too, so I can walk and continue working. Any thoughts on this while I puzzle it out? Thanks
