He recommended more exercise! I always expect doctors to push medications but instead he suggested working my body harder. And he was right. I’m more inclined to take his advice because of this.

He’s very nice but I wish he would be more assertive. Not ask me what I want him to do, but tell me this needs to be done. I think a wide boar MRI should be done on my abdomen. A few years ago it was found I have an adinoma on my adrenal gland. The dr treating me, moved and no one picked it up to follow through . I’ve had abdomen pain too.

Doesn't explain results. Doesn't write anything down or make of note of it. Very little communication between patient and doctor.
