Nurse and receptionist were both nice. Dr. Gavin S. was condescending at best. He started by making unwarranted comments about how I handle a disability for which I already receive professional treatment. As I said in-person, thank you but I’ve been dealing with this for 20+ years now. The disability was not at all related to his field of study, nor was it related to my appointment. After this rough start he interrupted me constantly and had no problem cutting me off while I was trying to answer his questions. Argued with me about referring to my past illness as “presumed covid”(despite being told that I was a presumed positive by a medical professional?) and would not stop until I expressly said “ my symptoms worsened after I had it regardless. I do not care what you call it.” I mentioned two other symptoms during flare-ups— stomach pain/nausea/diarrhea and extreme fluid retention in the day following. I am in the microbiology field; I suggested the possibility of mast cell involvement due to allergic symptoms occurring in multiple organ systems.. He responded by calling it “the new celiac’s” with a dismissive eye-roll, referring to MCAS-- which I had not mentioned. He would not listen when I said this, and cut me off to tell me a serum tryptase test at any point would prove if I had it— which is wrong. Serum tryptase is consistently elevated only in those with an increased number of mast cells. MCAS can be present with a normal number of mast cells that are hyperresponsive, in which case serum tryptase would be normal unless an attack was happening.I didn't bring this up then because I didn't want to appear as if I thought I knew better than a doctor, but a simple google search confirmed it. This matters only to attention the fact that he isn’t caught up on the most recent research in immunology and is passing false information to patients. I don’t think I have MCAS and I did not ask him to test me for MCAS. All I did was list symptoms and briefly speculate. He became frustrated with me and said something along the lines of “okay, well then what do you think you have?” (idk! you’re the doctor!). I told him I had speculated I was consuming an allergen unknowingly; he argued with that as well, claiming that food allergies are not IgE mediated (many of them are) and that I would “know” if I was allergic to something because the events would be reproducible (not if exposure happens unknowingly to small amounts, such as with cross-contamination) He told me that IgE reactions would be “immediate”. This is also wrong. I have a history of anaphylactic allergies and it can take up to a few hours; for me usually 30 minutes. To be clear, I did not at any point suggest I may have any one condition; I merely tried to present my logged symptoms (i keep a journal for accuracy) and thoughts about them as a scientist, to which he reacted with animosity and false information. He even went as far as to say my fluid retention was "impossible", which doesn't even make sense-- fluid retention is a well-documented thing that happens. I didn't even know how to respond to that. I didn't get to address my other symptoms because, well, what's the point if he's just going to say it's not happening? He reacted aggressively when i requested to see another doctor. My chart reflected that he didn't listen to me; he listed my stomach issues as "bloating and gas" when that is not what I described. He's correct in saying these aren't IgE mediated, but it's irrelevant because those weren't the symptoms I had. Nausea/cramping/diarrhea are all well-known symptoms of an IgE allergic reaction, and for him to not know this-- or to not listen without interruption for long enough to hear what my symptoms were-- is concerning. The appointment was draining, but I felt at least somewhat vindicated by his immature, dare I say even tantrum-esque reaction to being told VERY POLITELY that I wanted a different doctor "to avoid wasting your time or mine". It could have been avoided had you treated me with even a modicum of respect, dude!
