My wife just had ankle surgery to repair a clean fib break and hairline rib fracture . She is very fit, does not do anything pills even aspirin etc. occasional wine, 1 cup coffee etc. doc gave her 7.5-350 Percocet which she used maybe for 1.5. - 2 days max - 2 per every 4-6 hrs. Stopped Thursday night, woke Friday w splitting headache and mild nausea , chills etc. Friday afternoon she vomited once, feels generally better cept for the headache which as yet to subside today. She has some chills and feels fatigued w headache My question is can two days using that shit - pardon the language - cause this and what to do for it? Advil does ZIP btw. Can she take Tylenol?
