My husband goes to her. He is on BP meds. She doesn't do any checks on him or how his medication is working. She just refills his script. I don't think this is normal or taking very good care of any patient. I have to see my doc every 3 to 4 months to check my BP and do labs yearly. She should be doing the same. My husband goes to her because she let's him push her around and not follow medical protocol.
