Hello. Over a month ago, probably 35 days, I hit the top-left part of my head on the rubber frame of my car door. I was at work, got up quickly and hit it on the way out of my car. I noticed that it did hurt for about 10-20 minutes, i rubbed it and just shrugged it off. before that day i had been taking xanax for my acute anxiety, and omeprezole for my GERD because of my esophagus erosion. I didnt experience any serious symptoms, no problem with vision, balance, no bleeding, barely a bump, if that. I slept fine through the night and felt fine over the next 3 weeks. i got a headache about 2 weeks ago when i was smoking weed with a friend, while on xanax (i had a marijuan prescription for anxiety for 3 years now), and it went away after an hour. then earlier this week, starting on tuesday or wednesday the headaches came back again. at the same time i also began to have a nasal infection/ light bronchitus (which i may have gotten from my sister who i had seen last weekend who had bronchitus). is it just coincidence that im having headaches in the same area as where i hit it a month ago? is the sinus infection playing tricks on me? or is something else possibly wrong?
