My neck is killing me....Help!

[Calibrex]

Bridging on your head 10 or 20 times everyday will help a lot.That and learn how to keep them off your head. I suffered reoccurring back and neck injuries for a while and it taught me to not let anyone near my head. Really is the best policy.

Excellent advice.

Remember GeoGiant, Jiujitsu is not about meeting force with force. Your instructors should be able to teach you ways to deal with this issue. For right now, it sounds like you're trying to "out wrestle a wrestler." That's probably not going to work well for you.

pretty much right on. I wrestled for a year - and the main thing I learned was that size is a state of mind. I was always 2 or more inches shorter and weighed 25 lbs less than most people I practiced on. It was all about position. Keep moving, and try to get into favorable positions. If something is hurting, something is potentially wrong.

I had a bad back created from having a poor guard. I have seen friends with sore knees because of how they did transitional movements in defensive positions. And yes, sore necks will occur if you are using your head for positions/posture too much or your partner is getting you into rough pins/holds.
