Last night I was about to iron my nursing type C uniform for my first day Training. I was very excited by then. But just before I plugged the iron, I suddenly had a very severe left flank pain. I sat for a while and observe the pain. The pain is getting more painful and I started to have scanty painful urination. I drank a lot of water plus buko juice (good for UTIs). I diagnosed myself with UTI (urinary tract infection) but I am alarmed because the pain is confined in my left flank and I was positive CVA (costovertebral angle) and it is very painful even I was not touching the area. I was thinking of having pyelonephritis (inflammation of the kidneys) or renal stones on the left kidney. Because of the pain I decided to have a check-up in the hospital.
