Blood pressure. It due to high pressure!

I have normally the blood pressure of 115-125 to 60-70. I started worrieng about blood pressure so i started monitoring it more often. Until a doctor said to not check my blood pressure so often at this age and forget about it. But today after sitting in fromt of screen whole day i was feeling disoriented and tightness in head and wierd in body. So i thought what if it is from rise in blood pressure. So i measured it once and it came 132/ 80 in digital. I measured it 3-4 times and then it came 137-136 i thought why is it increasing and panicked. Now it is 123/65. Sir what was the reason for the rise. I was feeling pulling in my head and tightness. And sharp stab on side of eyes in head. Was it due to high pressure
