I don't really understand why your GP Practice is meedling with your medication when you are under a consultant.
I know my GP has nothing to do with advice when a patient is under a diabetic consultant.
I would have been phoning your consultants secretary and stating your case to get a quicker appointment if possible.
My GP practice is normally really good, they generally treat there own diabetic patients and don't send them to the local hospital, they have a Dr one day a week at the practice who works at the local hospital the rest of the week, they also have a GP Dr who mops up the rest, but I have no faith in him.
I was under this specialist at the practice for about 5 years and could see her whenever necessary, she was also backed up with a specialist diabetic nurse. Due to my own personal circumstances I stopped seeing her and eventually started to see a consultant at the local hospital. I am only allowed to see him once a year and am supposed to have a follow up with a nurse. This hasn't been happening. I have tried to see him before and been told I can't. I do know one of the nurses there who has been very helpful but they are very pushed. My diabetic care was actually much better when I was cared for by my practice. I have a phobia about drs and it takes me a long while to feel comfortable. Sadly this Dr at my practice is due to retire in a few months so I am unsure what to do now.
My GP who I saw today has been treating me for a variety of problems for the last 6 years and I feel comfortable with him, spoke to the diabetic specialist after my visit to as it was her day at the surgery today.
