Is this normal after an appendectomy ?

i had an appendectomy dec. 4th, no complication was released 3 days after surgery. about a week later i was back in the ER with trouble breathing, and chest pain did a chest x-ray and blood work said it was pneumonia sent me home with an antibiotic. they said they were not concerned with a clot due to the fact that i received 2 blood thinner shots so they didn't even check. now tomorrow is my last day on antibiotics and im still running a low grade fever also my abdomen has started to hurt and my back as well, also im still very nauseated and vomiting. like i ate dinner and within 5 mins i vomited half my dinner up *i know tmi * i dont know what to do ? im not going back to that incompetent ER they dont know there head from there asses. i cant get into see my surgeon till dec. 20th... what can i do until then ?
