Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You had laparoscopic
appendectomy operation, after 5 days pelvic inflamatory disease is diagnised, inspite of stopping food you have got watery bowel movements. You are also getting
sharp pain in the upper abdomen, and back, desturbing the sleep.
There could be so many causes , pelvic inflamatory disease would have been there before the operation, and its treatment would have been post poned, the medicines used for these two would have caused
diarrhoea, and gastric pain. Rare cause may be nonfusion of appendicular stitches.
I advise you to consult your surgeon for diagnosis and treatment. you may need to have M.R.I.besides other routine tests for confermation.
Wishing for a quick and complete recovery.
best regards.
