I m diabetic. Until one week ago, in control, with rising range of low 50 s. Rising to about 125 range after eating. A1C of 5.3%. Then a week ago I had a tooth pulled (#19). Now, my rising is 90, and post is 225 range. When my stomach is empty, it hurts, like a bad burning sensation. Plus, I want to vomit, but nothing comes out, except orange liquid (stomach acid?). Please explain this to me?
