Dear Friend,
Well am not suspecting osteoarthritis, but another form of
arthritis called as
Rheumatoid arthritis.But to be dead sure, we need to do a number of blood examinations-which includes ESR, CRP, CCP, RA FACTOR, besides the routine hemogram. In india, blood tests can be done on request of patient itself, but i don't know if same is allowed\accepted in your country.
So get these blood work up done, so that, we can go ahead with the discussion,.
