I was in a car accident several years ago and suffered from whiplash. Not serious at first and the MRI checked out OK. Then one day I was doing heavy shoulder presses (behind the head). Unlocking the weight at a strange angle screwed me up. I got a sharp pain in the back left part of the base of my neck, and an instant headache to go with it. I layed off the weights for a few weeks and everything has been fine for about a year.
The injury came back while I was doing heavy incline dumbell benches. Unfortunately the last (I feel most important) rep of any exercise will set it off. If I'm benching and I fail at 10 reps I'm fine as long as I stop at 8 or 9, and not 10. I've been going to a chiro and she says there is a spasm at the back of my neck. She suggested lightening up.
I don't want to stop lifting for too long. What should I do? Even leg pressing screws with my neck. I don't want to loose any progress. Any recommendations on how to go from here? The chiro has helped but the spasm keeps coming back. How should I modify my training? Thanks.
