My 40 year gaming life might be coming to a end

Where do I start: A few weeks ago I complained about pains in my head that was not headaches. My doctor asked me how long have I had these head pains. I answered just today. Doctor said if the pains hang around I would need a head scann. He thinks I might have a sist in my head. After a few weeks of nothing there was last night: Last night I played 4 back to back PoE level 28 games. On the last game I kepted getting pains in the top right side of my brain. What was triggering the pains was concentrating on playing to hard. My eyes could see everything clearly and they was not paining so it can't be my eyes. I'll play again tonight and test myself over the next two days. Playing and getting real life head pains from doing it could very well stop my gaming life of 40 years. I will ask a question: Did I get my wires crossed?
