On December 25th I began vomiting ,had diarrhea and had pains in my right lower back and front of my abdomen , i went to the doctor and he suspected appendicitis.I was admitted to hospital that night , the doctors there were suspecting either appendicitis or a ruptured cyst on my ovary.I was given a CT scan and it showed nothing in my bowels , kidneys or appendix. Instead it showed swelling in my right urethra.I got a blood test and my white blood cells came back as 30 , instead of the normal which the doctors told me is 4-11. I was sent home today as i was fed up sitting in the hospital and i still do not have a diagnosis. One thing i did notice in my urine on the first night there was a solid object , i was thinking kidney stone as after that i felt abit better,but it didnt hurt as i was urinating. Could this also be the cause of the swelling , any ideas?Im generally a healthy teenager. Depsite having Henoch Schonlein Purpura a few years ago , i have had nothing else any bit serious.
