Hi. I’ve been Pre-diabetic for 10 yrs on metformin SR twice a day. ( no regular blood tests or diabetic checks ups offered). Felt terrible for the last year, ask GP to be retested. And confirmed as diabetic. ( lost 11lb in four weeks with healthy eating- and I will do my best to turn this around). However. Metformin SR was increased to four tablets a day, which has cause stomach pain and wind and skin inching! Uncomfortable to even walk. Changed by GP to sitagliptin - just as bad. Sent to A +E via ambulance with gastric pain- given antibiotics- still in pain. Asked GP for referral to diabetic consultation and was told no. What do I do? I don’t test sugar Levels. Just have medication. Thanks for any help or feedback.
