This is Dr. David
I am sorry about your wife's knee
the swelling can be due to gout or arthritis or infection or synovial cyst
she can get blood test to check her uric acid levels to check for gout.
she has to get to a medical center for an xray.
why did you rate poor service?
I am still here to help you.
O.K. DR David..You have not really answered my question as to the possibility of a spontaneous fracture nor given a meaningful differential diagnosis. A doctor was called in who thought that this might be rheumatism..This is unlikely as there were no generalised joint pains or fever. The swelling is largely ourside the joint anyway.
