Our 13 yrs old son has been diagnosed with migrating viral arthiritis. He has been in anti-infammatory medication ( Advil , Naprosen and Relafen) alternately for 15 days plus rest. The doctor said that this intense pain that has been migrating from one joint to another throughout his body can continue for another 3 to 5 weeks. We are desperate as our son is incredibly active and joyful and this situation is so incapacitating. Is there anything else we can do? Have you seen this type of situation in other 13 yrs old boys. In his school there has never been any other case and we had never seen anything like it anywhere else. Dr. dais the main cause was a common cold that he had before symsptoms started.
