Yep. Got new glasses, then got terrible headaches. I took them back to a different place in the same company (closer to work rather than home this time) and they re-checked my eyes and found that the prescription I was given was totally wrong (bifocal lenses when I really only needed single vision ones!). There were no problems at all in getting them fixed up.

Definitely go back - it's not worth screwing around with headaches and not feeling/seeing right. And I've also been reminded that I'm seriously overdue for an eye test!
