"Lower right abdominal pain"

I first got taken into hospital a month ago, with suspected appendicitis, had blood test, pregnancy test and urine test all normal and preg test negative, sent home after hours of waiting at hospital with this pain, then got taken back in for the same pain they done the same tests and said it could be appendicitis again, then got discharged again! Went to the doctors yesterday and got rushed into the SAU with suspected appendicitis, done the same tests and nothing showed up, got discharged and went home after hours of being in agony. Today I got a call asking me to come in again for a ultrasound scan that showed up bleeding which could be caused by torn lining of the ovaries or womb, and although I have internal bleeding i have been sent home! This is absolutely ridiculous and i will never be coming to this hospital again, I am still in agony!
