My blood pressure is normally fine, but sometimes I feel hot in my head and have a dull deep ache in my head, when it is like that I have found out my blood pressure is high 158/112. I dont know why but I ussually just wait and it all goes away after a couple hours and blood pressure. goes back to normal 120/75 or 80. Does that tell you something is wrong if so what and what should I do? I`m 57yrs old 5`6" 210lbs, yes they say I am obese according to scales, I have a potbelly that developed at 31yrs old,every man in my family gets one about that age and there is nothing that can stop it, I TRIED! I have no energy at all, it doesnt seem to matter what I do nothing works.
