My wife's left knee area is swollen and painful at the cap. We are not sure but it thought may occured after an injection in the buttocks after pregnancy abortion. We have used cyprotab twice and ha joined the cyprotab the second time with flotac and baclofen use as directed by the physician. no blood test carried out thus far. the swelling is still there as well as the pain. Please help with possible diagnosis, prognosis and alternative treatment.
