Hi angelfiregirl, welcome to the Type 2 diabetes community! I know you asked about high blood sugar, but I also wanted to share the signs and symptoms of low blood sugar from MedHelp.org and the Sugar Sense app, in case it helps you in the future. You can find these in the Stay Well section of the Health Guide in the app.

Hi,
Feeling a choking sensation from high blood sugar is not a typical feeling.
Please consult your Dr if you continue to feel unwell.
