Hate saying this as I feel like a right pansy complaining of neck ache!

Anyways, I've only had my storm a few months and am really enjoying it. Unfortunately, over the last couple of weeks I have had an extremely painful neck and headache to the point I had to take time off work and see a chiropractor. I've never had any problems like this before. He reckons the likely cause is the riding position on the Storm as I do a few miles on it, roughly 300 a week. Previously I had a bandit and again suffered no problems.
Have any of you mob had similar problems? And do you reckon raising the bars would help? I know it is meant to help with wrist ache but I haven't had a problem with my wrists. Raising it less than 2cm seems pretty minimal to me.
Cheers for your advice.
