New pressure right at the top of my head

Hello everyone,

Hope you all are keeping safe xx
I have this weird pressure right at the top part of my head, it stops for a couple of seconds and then returns. I’ve noticed it since last night.

there’s no pain or anything, just a slight pressure feeling. Makes me a little anxious thinking it’s something like high blood pressure or brain tumour.

Anyone experienced this before?

Thank you in advance!

tension headache etc etc

you have HA so automatically think the worse
