Thanks for the reply my hbA1c blood test was 58.Ive been to the nurse twice now with these symptoms and im still getting them her response was your only type 2 and your blood level wasnt high its when its in the 90s that we worry .I had my breakfast this morning at 9am and took my metformin with it 2 hrs later i had a dry mouth ,sweating and not felt good all day I now have sores on my tongue which are really painful because of the flippent attitude of the nurse its making me not want to go back
How long have you had the symptoms? Your HbA1c is what I would call moderately high, rather than very high. It covers the last 2 months. So it is possible that your high BGs have only been for a few weeks, which could explain why your HbA1c is not higher. T2 comes on gradually but T1 comes on more suddenly, so without knowing your fasting BG, it's possible your HbA1c has only picked up on very recent high BGs.
I think you really need to test your BG at home. You can buy a meter and test strips at a pharmacy if you want them sooner than buying them online. Online is cheaper. The SD Codefree has the cheapest test strips, which is the main ongoing cost of testing.
I would not be surprised if the blood tests your doctor/nurse ordered were only for HbA1c and not fasting BG. In the past they only tested FBG. This has switched to mainly HbA1c instead. But there is a problem with doing it this way because some people's diabetes is unusual and if you don't know the FBG you can miss that. Rather than try and get further help from them, at this stage I think it would be more fruitful to test your FBG yourself, plus the info from frequent testing will be valuable in itself as you learn how to manage your diabetes.
The sores on your tongue could be mouth ulcers brought on by stress, or could be oral thrush, or an infection (which can also cause some of the other symptoms). When we are run down, we tend to get sores like these more readily. I think you should get a doctor to look at your tongue. You could go back to your existing doctor and just focus on getting the sores diagnosed (he should be able to handle that), or you could find a new medical practice who are going to do their job properly with regard to diabetes. It's hard to know beforehand how good they are, though.
If you start feeling even more unwell before you can see a doctor, you should call NHS Direct on 111 for advice or go to a walk in centre or A&E, because we really don't know what is going on and it could be more serious.
Sucking on an ice cube might relieve pain in your mouth. Paracetamol would help too.
I checked the listed side effects of metformin and they include muscle pain, tiredness, headache, sweating, fever and "flu like symptoms". I didn't see dry mouth or mouth sores there, but these could be related to high BGs or something else.

In summary, I think you should see a doctor about these symptoms, which could be caused by high BGs, metformin, a virus or something else.
