hello,
as you said, if you have your
appendix removed then the related symptoms must subside.
yes, the right side pain is suggestive of
appendicitis but that is not the only condition which causes right side
abdominal pain.
yes, the reason because of which you were hospitalized because of the local infection at appendix site, and this was dealt with with antibiotics, this surely could make appear the related symptoms.
see, this might be the prominent cause.
it could have been happened that some minor infection would remained uncleared there and which on the passage of time grow sufficient enough to cause you discomfort.
and this through the course of time grew large enough to get you hospitalized. and ya , in the case of heavy infection, surgery is not recommended and the condition is better treated conventionally through antibiotics.
if the appendix is not the case, then there is another condition known as meckle's diverticulum, which is a similar projection from
small intestine just as the appendix and which in the same manner might get inflamed uttering the same symptoms.
either of the thing could be the reason for the condition you are having.
thanks
regards
