Unless it hurts, it's not a problem. People -- especially younger people who are in good health - can safely "pop" their neck. Just do it at a slow speed, and stop if it starts to hurt. Don't crack your neck like a whip :} (I bet you guessed that one already :} )
You may have a problem with your brain. Throbbing pain in the back of the head is a sign that the back of your brain is slightly lower down your neck then it should be. I have this condition myself. It is not a problem you should be very concerned about as the only thing this problem causes is headaches.
You are reading way to much into that. If you like him talk to him, and find out! ;)
Sounds to me like a cracked head and or a blown head gasket, i had a similar problem but it was on a Saturn
Neither, they incline left or right.
you need to see a doctor about that one. sorry!! something is wrong.
You go and see a qualified medical practitioner (a Doctor) about your problem.
it stays on , it has dowel pins sorta to guide head and hold gasket
ya i have the same problem i have two inward bumps in the back of my head top backish i think its normal
Part of my problem was that my core wasn't strong enough so I couldn't pull them quick enough. lay down on your back and hold on to a person's feet (or a wall pillar) and pull your hips towards your head in the tuck position. back down. up. down. It worked for me. And hey stronger abs are always a plus!!!!
Keep Ur back straight up and down
No.
The blood can slide down your throat.
