you've been dealing with a migraine for two weeks too? Or the back/neck pain? I suffer from the occational migraine but i've never had one last for more that two days. usually back/neck pain is associated with a pulled muscle. the headache and back/neck pain might be two disparate issues. Given that you've only had this for two weeks, I'd take over-the-counter anti-inflams and rest. call your dr if it continues much longer.
good luck...
when did this start? what were you doing?
