but I’d suggest that the doc is pretty confident it’s not acute appendicitis if they haven’t even sent her to hospital for a bit of a watch & see
prodding the belly of somebody can tell quite a lot if you know what you’re doing (apparently !) – appendicitis pain “classically” starts off central when it’s just your gut hurting and then migrates to the right if inflammation develops on the abdominal wall. How the patient behaves while you’re pressing and then releasing pressure tells them things too.
If you want to reassure yourselves (or unduly worry depending on your nature) see if Medscape has a section on appendicitis. It’s intended for professionals but I’d say relatively easy to read if you’re cleverish
(one of my kids always got bellyache when she had a virus – there’s lots of lymph nodes in there)
Hang on, here we go – Medscape you may need your wife to translate – it’s in American 😉
