2weeks ago my roommate dropped something out the freezer. I quickly bent down to pick it up and quickly came back up. I banged my head on the corner of the freezer door. I was in pain for a few moments I was a little shocked how did the freezer door close. I've had headaches and pain in the middle left side of my head. Lately I've been having severe headaches during the evening where i feel a lot of pressure in my head when sitting and standing. This is the third night straight my head has been hurting severely. I took a pain reliever and my head still hurts. I can not lay on my left side without it hurting more. Since I banged my head I have felt dizzy lightheaded and nauseous throughout the day. In the late afternoon early evening my headache is very severe to a point I could not sleep last night.
