I had a colonoscopy yesterday. The doctor used propofol to put me to sleep and there was oxygen in my nose. When I woke up I was hurting all over, had shortness of breath, the death rattle when breathing and my throat was raw. The doctor assured me he had not put anything down my throat. Anyway, after I came home I was very cold and could not get warm, nauseous, no appetite and I was coughing up some blood with thick yellow mucus. I took pain meds and I quit aching and warmed up. I didn t know if it was coming from my chest or sinuses. Today I took a hot shower and used my nettie pot, but still am having the shortness of breath and the rattle in my throat. The rattle is much worse when I lay on my left side. I called the Dr. who did the colonoscopy today and his nurse said for me to go to the ER. I hate to go to the ER if it is something simple as my insurance is not very good.
