Pain on right side of head accompanied with dizziness and lightheadedness?

I am 17 year old male. I've been experiencing random strong pains on my head for like 2ish years now. It just started with a random pain always on my right side and it hurt and it startled me whenever I got them lol. They were scary. And also since last year, whenever I would lay down and get up I would get really dizzy and my vision were blurred. Then probably since October, it has been getting worse. I wake up with a headache and only for like the past 2 weeks have I been feeling lightheaded and dizzy. The dizzy spells from getting up to fast have not been present but I constantly have the dizzy feeling every time I turn my head. It's bad but it's not bad. I ran cross country from August to October and I also drive to school. These symptoms are minor but to me they are scaring me. I will be going to the doctor soon.

Also I have like no history of ear problems just like maybe 2 ear aches when I was a kid. Could this be an ear problem? I don't know anymore lol

Thank you for your help!!
