I visited a friend last night that I hadnt seen in a while and he greeted me when I wasnt looking from my right side by shaking my head from side to side vigorously for about 5 seconds before I yelled "stop".
As he stopped I felt the blood rush to my brain type feeling. It had also felt like I had
1. Fallen off a bunk bed
2. Someone hitting me with a hammer on my head
3. When you get fouled in football it felt like as your falling down you hit your head against the grass.
I remained conscious but have had a weird headache for the last 24 hours now.
Can I get bleeding from this?
Can I get brain damage from this?
Can I get anything I may not be aware of from this occuring?
