Sick after Wisdom tooth removal.?

Well i got one wisdome tooth removed this morniing it went fine, i got home took my antibiotic and my pain meds and felt good so i ate some ice cream and soup. hours past the pain began coming back so i took half of one of my percocettes cause i didnt feel i needed 2 like the dose said. I layed down for a bit fell asleep then woke up with the most severe migrain i have ever had in my life! I couldnt stand it i was shaking and i have been vomitting. I tried to take iburophen for the ead ache and some stuff for my stomach but i couldnt hold it down. Im also concerned because i know your not even supposed to spit after wisdom tooth extraction and not only did i have to spit but vomit! I have taken percocettes before and they didnt have that effect on me, im unsure on why im feeling this way any advice"?
