Hi & Welcome. I can understand your concern for the joint pains following Chikungunya fever. Usually the residual joint pain following the attack of Chikungunya persists for some time and it responds well to anti inflammatory drugs like Ibuprofen or Diclofenac. Since it seems these drugs are not helpful in relieving the pain, then the possibility of inflammatory joint conditions like rheumatoid arthritis must be ruled out. You are therefore advised to consult a physician for certain lab tests such as CBC, ESR, C reactive protein, Rh factor, Anti-nuclear antibodies, Anti CCP antibodies to confirm the diagnosis. Meanwhile you may take tab Indomethacin for the symptomatic relief of pain along with Pantoprazole to prevent gastritis. Hope the suggestions given above could be useful to you.
