But is diarrhea a required symptom of stomach flu?

Not at first. When you first get "a stomach flu bug", your gut may protest it by trying to shut down altogether. In this stage you feel the nausea and vomiting, because stuff just does not want to go through. It's usually later that the body tries to "wash out the virus" by dumping more fluids in the gut to try and wash out the virus - and then boom, diarrhea. So early on you may not poop at all.

Hey, I think I might have appendicitis because I have the following symptoms; pain in lower right abdomen, diarrhea, and fever. Or is it stomach flu?

If worried, see doc. The classic symptoms of appendicitis are abdominal pain localizing to the right lower quadrant (rlq) of the abdomen, some nausea and vomiting, and lack of appetite.

Need checked out. My first advice to you is to get this checked out sooner rather than later, even if that means a trip to the er. A ruptured appendix is much more difficult to deal with than one that has not ruptured yet. One easy way to see if it may be appendicitis is to jump up. If the pain is made worse when you land and is confined to that right lower quadrant, then more likely appendix and not stomach bug.

Is it possible to have only vomiting but not other symptoms (not even diarrhea) for a stomach flu?

Initially, yes. Vomiting is a presenting symptom with intestinal viral illness, since it is often a secondary infection to respiratory viral illnesses, but with peristalsis and gravity to assist viral exposure, the lower GI tract eventually gets exposed and symptoms will progress to abdominal pain, cramping, and diarrhea, mucous in stool, and in severe cases GI bleeding.
