Hi.I Wanted To Ask Advice Regarding Headaches. I Used To

Hi.I wanted to ask advice regarding headaches. I used to love playing video games and had no problem going for hours. For two years now I have been plagued with horrible one sided headaches. They feel as if they are behind my left eye. My head feels swollen with pinch like pains. After a while I gave up video games and using my phone a lot and the headaches subsided. However I decided to try a video game again and the headache was back however I now for 6 months have a feeling of my left ear being blocked, a loud vibrating humming I it and it wont pop. What's going on I am depressed.I am tired of headaches and noises in my ear...
