Be sure to ask if the person doing your checkup/assessment is an actual doctor or just a PA. This is in no way meant to belittle a PAs work but the PA I had today had no clue what was actually going on with my knee. When information provided negated what she thought was going on she finally brought an orthopedist in to look at my knee and I was finally given an actual answer as to what was wrong. Very thankful Dr. Liu stepped in and was thorough in checking the PAs work/'assessment' of my knee.
