Eric, are you still hauling around a camera bag? or say a laptop case or a back pack using one strap. Next question, do you sling it over the shoulder on the side that's currenty having the neck pain?

I used to haul my laptop PC back and forth from work using a computer case backpack, and would sling it over my shoulder with one strap as one does, and wonder why that side of my neck felt exactly like the other side that had the tumors did pain wise. Then I switched to rolling wheel case and within a week the pain went away. Went back to the back pack, and the pain started up again.

Didn't take much time each day for it to start, just the time from my apartment down to the car park and various running around.

Just a thought from my experience anyway.
