    My Doctor explained to me what was wrong and what I needed to do to get better. I have seen him several times and he has been really good for me. Thank you.
    Touch based with my previous tests
    Everything is very good
    Was told after a specific test was taken on the phone that the provider wanted a 10 minute session with me. This session was provided to me after my 4th call to the office to check on the follow up. There seemed to be no sense of urgency involved, until I met with the provider. I was urged to have surgery soon.
