migraine and childbirth

No, I can't say I have experienced it, I'm surprised to say, but my daughter did. She was given demerol and phenergan for pain and the migraine was the result. She had a reaction to the mix. The doc thought it was the phenergan but my daughter had taken this drug during her pregnancy for severe morning sickness and had not had this type of reaction. During labor, after the shot, her blood pressure shot sky high, she grabbed her head and moaned and was having hallucinations . It was really scary. ( I was her coach) Linda Sorry, I meant to write Demerol tabs, I know there isn't tabs for Nubain, the only time I've had Nubain was during labor a few months ago. I was stricken with a severe migraine during labor and and after delivery, so this helped with that to, not just the labor pains. Has any others suffered like this during the delivery of their children?
