i had both appendicitis and pneumonia when i had to have my appendix removed
had a fever of about 104, mad nausea, fades in and out of consciousness, and vomiting, not to mention god awful abdomen pains. literally feels like someone is twisting a knife into your stomach. appendix ended up bursting, so that was fun.
apparently it was a miracle i was healthy enough to survive the operation since i was so sick
