Should I call an ambulance?

I have the flu right now. Been on tamiflu for 2 days now. I also have severe endometriosis. I can't tell if the pain is from my endo or not it's usually in the lower right side down toward my hipbone. This pain I'm having is ALL over my right side. It feels like only my right side was hit by a freight train. I can barely walk. I am sweating and dizzy from the pain. At home by myself right now and starting to get scared. I know I couldn't drive myself.
