I was disappointed with my recent annual physical exam. I expected a more thorough physical examination, but it felt very brief and incomplete.The PA spent most of the visit reviewing my chart , but very little time was spent performing an actual physical exam. I expected a more comprehensive assessment, including a more careful examination as part of my annual checkup.

The care provider I saw was excellent. It is often a very long wait to see the doctor for routine care.

I have found the physical therapy exercises Keli recommended to do at home very helpful in alleviating some of my problems.
