Here's the scenario: I've had repeated swelling in my right knee for several years now. It's currently swollen to a size I've never seen before, rendering my leg stiff and of minimal use. It hasn't happened for a little over a year. Anyways, I'm concerned because it's always the same knee and it recurs. I went to the hospital a few days ago, and they x-rayed the knee to find nothing wrong with the bone.
I was referred to an orthopedist, who I saw this morning. She drained 85ml of joint fluid from the knee and sent it off to a laboratory for testing. She then ordered a blood test for uric acid and something else (forget exactly what). I got a call later today saying that they suggest I get an MRI and my insurance has authorized it already.
I'm certainly not a doctor, but I feel like this is moving very fast and the MRI is excessive. I would have thought that the joint fluid and blood test would be conclusive enough, am I wrong? Even though my insurance covers an MRI, it's still probably very expensive and I'd rather not do it if my doctor is just ordering the test without crucial need.
