Question for Betty.
 

I have been having these jolts of . . . something going down my arms and legs.  I'm not really sure how to explain it but it feels like an electrical shock but, without any pain; kind of like when you go to move a muscle but then change your mind at the last second.  It doesn't happen all the time and when it does it's mostly when my eyes are closed and I move my head.  I also notice that when it is happening I feel a little light headed.  It never hurts, but it is starting to worry me because it doesn't seem to be going away.  Any advice would help. Thanks!

You may have a very simple case of a "pinched nerve" or something more serious.  A pinched nerve sends garbled messages to the brain, such as feelings of numbness, burning, or tingling in the area in which the nerve is compressed and also down the entire path of that nerve. It may be that the nerve is being compressed when you turn your head in a certain direction, and released when you move it back. 

You may want to exam your posture when you are studying or using your laptop, your sleep position, and even the amount of weight carried in your backpack to see what is causing this problem.  You may want to start doing some gentle stretching, take frequent breaks and changes in position when you are studying. You may also want to lighten your backpack.

If you experience tingling, pain, burning, or numbness in your extremities that lasts for awhile after you change positions, or that occur regularly, it's time to see your health care provider.
