been fighting really bad headaches for a couple weeks now n talked to my nurse yesterday afternoon (it's now 3am) about them. she said if I still had one in the morning to call n they'd have me come in for an IV and whatever else... well I took tylenol an hr ago n still no relief at all not even a little bit. even tho its 3am and I was gonna wait til morning like a decent time that is should I just go in to the er or what should I do?? my head in pounding and it's only my right side right now by my temple but can't sleep like this. I even tried rubbing some Vick vapor rub on it which helps every now and then which I put on a half hr ago n still nothing. I'm nauseous right now too. idk whether to just go in now or try to wait it out a bit longer n call when they open or what. been taking meds all night every 4-5hrs and no relief :(
