I am having knee swelling and pain from 45 days. Doctor told I am having water in my knee and removed se fluid. But pain did not go for a single minute even. Then thy sent fluid for test and told its remetoid arthritis having one test positive n one negative. I consulted other doctor and he told he need to diagnose. He prescribed me bonek2, disprin, other pain killers but any how swelling is not reducing. I do not have any pain in other joints or left knee. not able to diagnose what m suffering.
