Stiff Neck- New Glasses

There seems to be a recurring theme with my new glasses- I had them taken back and they were supposed to get fixed- they had mistakenly been made on brown frames, not pewter. It took ages to get them back, then trying to get used to them again, then a whole week with a stiff neck, and even going to the chiropractor on Friday...I think I will need to take them aback again. They are just not working out... problem is that my old ones needed replacing last August, and I really need the improved vision.
