Couple of questions please.

Hi. So - what is your current HbA1c? you say your "numbers spike", what does that actually mean? And when you say your "pee feels hot", is that temperature, or a burning sensation?

It's really hard to know how to reply without that information. As you know, no-one on here can or should try to diagnose anything - but some people might have experienced something similar. It's perfectly normal for blood glucose to rise (and fall) in response to a range of things, only one of which is food. And the other thing is that not everything is caused by diabetes.
