I can’t keep anything down not even water I’ve been throwing up since 330 this morning l. So much pressure in my head and it will not go away. I’m having shortness of breath and I’ve been blacking out or seeing spots. I took a nap to see if that would help and I woke up shaking and sweating. This has never happen to me before and I can’t call my dr cause he office is closed today.
