Headaches from Medication?

Does anyone else get really horrendous headaches from time to time while on pain/nausea meds?

I've been to the ER a few times, with headaches so bad I was vomiting, couldn't stand up, and couldn't have anything at all touching my head.

When it's not quite so bad I tough it out at home. This happens to me maybe every couple months, sometimes more often.

I was told dehydration could be a part of it, but what about the meds themselves?

obviously headache can be a side effect of some of these meds, but so bad?

 

It could also be high/low power fronts, change in hormones, certain foods. My neurologist had me keep a trigger notebook. That really helped cut down my migraines. He also said normal OTC meds can cause it. Tylenol causes rebound migraines for me.
I'd talk to him and see if the two of you can work out a way to identify your triggers. Good luck.
