Seeing the doctor again doesn't guarantee that you will have surgery. Ultimately he can advide you on the best course but the ideal doctor patient relationship is that of an agent, i.e. he advises you to help make the best decision for yourself. So if you are actively avoiding an operation, it's up to you, unless you are incapacitated and the medical concensus is that it is necessary to save your life to have the op. Generally speaking, although appendectomies are one of the most common surgical procedures performed, all surgery, regardless of how minor do carry some risk. This will be advised to you before you sign any consent. You said it went away, ask the doctor how likely it is to go away again. And currently, how much bother is it? Is it worth surgically treating? If it is affecting your daily life adversely, I wold personally opt for the surgery, as it is relatively simple, very common and low risk. If left untreated, the problem could develop into something more sinister, ultimately into a burst appendix which can lead to very serious infection (Peritonitis) or sometimes bleeding. However if the doctor thinks it is not likely to advance to this stage, then why not wait and watch? The bottom line? I'd go and see the doctor and see what he advises, then make your own mind up.

Appendicitis as actually an inflamation of the appendix. Sometimes it will calm down for a bit and recur again and again. I would see the doctor and talk it over, and discuss your options. The one aspect you must be careful of is the appendix bursting, which can be very dangerous and requires emergency surgery. You may just opt to have them removed, because the sugery is quick as is the recovery. Good Luck.
