why do i sometimes feel an electrical shock in my head

[hectorh1992]

It doesn't always happen but when I'm playing football and I throw the ball to hard (as in with all my strength) I feel a weak and small electrical shock in my head. If I attempt to throw the ball with all my strength again or even with lest power, the shock happens again and the pain increases and lasts a lot longer. the first shock will happen in a instant and the pain will last for about 3 seconds. the second shock will also happen in a second but the pain will last for about 6 to 9 seconds. The pain is also a lot worse the second time. this happens to me every time I try to throw anything with a lot of force. I play a lot of different sports such as baseball, football, and handball (a form of racket ball where you substitute the racket for your hand) and when I pitch the ball, play as the quarterback, or swing to hit the handball powerfully and miss the ball, resulting in a excessive swing of my arm, I get an electrical shock to my head. I'm very carful not to let this happen and will say this only happens to me maybe 2 to 4 times a year. the worst pain I ever felt from this was around the time it first started happening to me when I was around 16. I am 22 now. at the age of 16, it happened to me three times and the third shock made my cry, gave me a headache and it was the last time I ever pitched a ball or threw a football. any ideal why this happens to me?

I used to have something called Tinel's sign. When I tapped my wrist lightly, an electrical shock would run up my arm.

Sounds like some nerve damage, possibly in your neck.

It could be something as simple as a pinched nerve.In MS there is Lmerittes Phenomina usually when bending forward. It sends shock sensation down your arms into your hand.

I have a similar problem, but only when I throw a ball with my left (non-dominant) hand. The pain is on the right side of my head though. I think it has something to do with the fact that the right side of your brain controls the left side of your body. Have you noticed which side of your head the pain is on?

I'm no doctor, but I think it's this:

i am very sorry you have this horrible pain.  By posting in this forum, my guess is if you are wondering if it could be MS or not.  

Have you seen a doctor about this?  Have you had any x-rays if other tests run?  My first thought is that it could be an injury or something going on with your spine.  Cooper Manning, older brother of Peyton and Eli, had spinal stenosis.  It was quite serious.  If he was to be hit a certain way, it would have had very extreme consequences, so he had to quit football.  

Also, there is a condition called trigeminal neuralgia. It can cause electrical shock sensations that can bring a person to their knees.

Without other symptoms correlating with MS, I don't think it is MS;however, I am not a doctor.  I would see a neurologist or your primary doctor ASAP to get this checked out. You want to rule out anything going on with your spine.
