I am a 19 year old male and I am scared to death.

I started off feeling some "movement" in my head. I was concerned but easily ignored it. After some time, it grew into a small but irritating headache. It comes on and off. When I press onto a certain place on the right side of my head, I feel some pain that goes down my neck. When I am lying in my bed and turn over or switch positions, I feel the headache worsen. Sometimes I feel dizzy or have a small migraine but it doesn't affect me much. Lately I have been involuntarily twitching, mainly my feet and legs. Sometimes when I walk, I start feeling "pins and needles' in my legs, especially in my thighs and I do get dizzy here and there.

I googled my symptoms(which could have been a mistake) and have essentially become a brain tumour expert but I really am afraid now because these symptoms align with a lot that I have seen online. I haven't told anyone because if I say "I think I have brain tumor" they probably won't take me seriously.

As I type this, Ifeel dizzy and can't wait to dive into my bed

So, what are the chances that I actually have a tumor?
