Few weeks ago the doctor had suspect of sleep apnea. he found blood pressure 160/100 today i checked my bp again it was 139/99. sometimes i have pain for seconds in the middle of my chest i'm not sure if left or right. what can this be?

Sleep apnea is dangerous and you are right to seek adivice. You need a sleep test to confirm the condition and if it is occuring you will need to lose weight, have a sleep apnea devise made by an expert, and get your blood presssure down. At 31 years of age you should be at 120 over 72 - 80 (mm Hg) Hike around that lovely island and thank you for what your country did during the war.
