Although they are very nice, I just don't leave this provider feeling like I have any questions answered. I feel like I got more from chatGPT, about do's and don'ts and diet and an actual plan on how to attack my condition. They just listen to what I have to say and then end the visit. I was told via the health portal that my labs were "good", but what does that mean? Do I need to continue the medication? Will I be able to go off meds now or soon? Have the things that I have changed helped my condition at all? I don't know.
