The doctor called my daughter during my exam. She explained the blood test results, the various medications prescribed and answered questions they had regarding my healthcare.

I was not very happy with my experience this time.

This provider had no bedside manner. When I asked for issues with the drug, I was told every drug has problems, don't worry about it. I don't think that was a very good response to a patient asking a provider about side effects of a drug.
