You are having an acute abdomen
which could be treated first by ruling out the possible diagnosis of Right iliac fossa
( clinical examination of abdomen and rectum, abdominal ultrasound by a radiologist
or surgeon, then other blood works up like full blood count, CRP, ESR etc could be done to support diagnosis)
2. Nephritic colic/ kidney stones/ pyelonephritis
etc ( urinalysis+ kidney ultrasound)
4. Ectopic pregnancy ( pregnancy test +, pelvic ultrasound may or may not show)
6. Pelvic inflammatory diseases
These are just a few among the numerous differential diagnosis for right iliac fossa pain. Which needs to be carefully examined by your doctor, one after another.
I will suggest you meed a visceral surgeon to handle your problem. ( don't be alarmed, seeing the surgeon doesn't necessarily mean you will get operated, surgeons are simply good with acute abdomen issues).
Hope this helps
