Hello and welcome to HCM
I read your mail in detail. Yes some thing is going wrong likely with Blood sugar level. I am not saying with Heart because you have only one or two reading of raised BP, it may be due to anxiety
or the activity you have done. Keep a check on it. But reading of blood sugar cant be wrong 292 is quite high, starts your medication as early as possible.
My advise to you is that go and get your Cardiac check up done by a Cardiologist, and he is a better person to decide whether you need medication for Hypertension
