more joint pain & swelling

Hi , I had written before about some swelling and pain in my left hand. After it was almost healed then my right had started having problems, I could not touch my thumb to my index finger and the bulb of my thump and back of my hand were puffy, and I could not use my hand. Then two days later my knee was swollen,painful, and I needed to wrap it to walk. I talked to my Dr and he had me take 2 anti inflammatory meds every 4 hours(ibuprofen). I am calling him again today. He has not had this come up before and will likely send me to a specialist to find out what is causing the problem. Has anyone else had experience with swelling and arthritis type pain in their joints. The fatigue and weakness I can handle, but this is hard....it really tweeks the depression
Thank you for any help you may have.
