Why does my head hurt so much and have so much pressure and pain when I bend over is it a head cold feel dizzy to?

What a pain! Depending on how long you haven't been feeling well and if you have thick colored mucous, you may be suffering from a sinus infection. If you have pain in your cheeks or forehead areas associated with nasal congestion, it may be a sinus infection, allergies, etc. It may benefit you to seek medical attention if you do not start to feel better. Also, using nasal saline spray every 2 hours or so m.
