Thanks for posting your query.
Do you have other symptoms such as watery shit/ vomiting/ fever/ burning sensation and increased frequency of urination/ foul smelling discharge from vagina?
Lower abdominal pain
may be due to acute gastroenteritis/ urinary tract
infection/ uterine in origin/ acute diverticulitis/ IBS and acute appendicitis
Acute appendicitis causes pain in right lower zone with vomiting and fever.
According to your history, there is chances of IBS. Pain on pressing occurs in IBS as patient may have spastic & hypersensitive colon.
You should consult with physician/ surgeon and should go for ultrasound
imaging as preliminary investigations.
