Pressure & stress in head. Thanks a lot.

I seem to have developed recurring issue in my head. From past 1 month as soon as I wake up in the morning , slowly a sort of pressure or tightness starts to build inside my head, (seems more on back of head), slight sense of constant nausea & uncomfortable feeling. This tends to go away if I don't think about this and spend time with group of people, but it's getting impossible to not think about this tension in head. It's more bothering if someone disturbs during sleep/ or have bad dreams. Some time it's too high and intolerable type of pressure inside head followed by slight numbness. Feels like my head is going to blast. It's a different feeling from headache which I never used to have earlier. I also feel weakness in hands and fingers, this also tends to increase when I think about it. I am 30 years old, height 6ft and weight 75kg. I did all blood and urine test and is normal, mri scan normal except some minor issue at c spline C5 & C6,( neurologist said is fine). THANKS a lot.
