Pressure in head with tingling in hand.

This has been happening occasionally for months at this point. Just to say I have already had a brain MRI 2 years ago and it said mild sinus mucous thickening other than that the report was said normal. For last 8 months atleast I have started getting horrifying sudden pressure in my head. It almost always happens while I am laying on my bed and 90% of the time after waking up. It's usually sudden and pressure (not pain) at an area of my head usually left. It feels like something is grabbing that area and tons of pressure. Before it used to just happen and go away, but my recent episode it lasted for 3 mins and started right after I woke up in early morning. I woke up still laying on my bed little sleepy haven't moved. The second I moved the pressure started with prickling sensation in my left hand index and left hand thumb. Other fingers felt fine. This lasted for 2-3 minutes. No other symptoms. The last episode was few weeks ago. The episode I had before that was 1 month ago.
