Thanks for your query.
From the sketchy information, it seems that you have either osteoarthritis
with acute swelling of the knee joint; or, it may be an acute attack of gout
(since the joints of the great toe too are affected).
Consult your treating doctor who will order for Serum Uric Acid test and, if required, CT scan
of the knee joint. Depending on the findings of these tests, he will prescribe appropriate medicines.
