Thanks for the query to H.C.M. Forum.
Migratory joints pain from one week after virus infection may be due to , Rheumatoid arthritis
Chkungunya , Epidemic polyarthritis
Whether there was rash or not?
You mentioned that there was virus infection , so blood culture
will find out the exact nature of virus .
Virology will help .
Get in blood for rheumatoid factors, with antinuclear antibodies
, E S R ( if raised indicate bacterial infection).
Treatment as morhine robaxin
, percocet all are symptomatic treatment so consult a physician and get complete blood as well virology reports to evaluation of diagnosis.
