Hi Vanessa, read your blog and I can empathise with you about this.
I've never felt able to talk to my GP regarding blood work and so I opted to ask the receptionist who was as good as gold in giving me the results even though it isn't exactly an ideal thing to do lol! I'm now putting a subject access request through instead as it saves me the embarrassment of having to go through my GP and saying it's for my own reference. On top of that I'll have something to look through and a paper copy of this is more helpful to me. I'll still have to explain as to why I want the information but I'll be telling the receptionist this, so it won't be as embarrassing for me!
I can understand about things being a battle, but conversely before I changed surgeries I went to two nurse practitioners and they both noted I had a goitre. I go to my proper doctor and they tell me I haven't! It is frustrating I know and I have thought about a referral, even going as far as registering with a private thyroid doctor, but I don't think they come cheap and I don't work so to find money for consultations and treatment isn't something I can conjure up right now!
I haven't had the misfortune to have a locum doctor, but the first one I had at my new practice was one in training. With my practice any patient can see any doctor, but I guess it depends on the surgery.
Hope you get things sorted out soon!! xx
