2 years ago, I had lower abdominal pain and fainted while I was in class. I was taken into ER and treated with bladder infection. I was given some medication, and my doctor told me that the medication can turn my urine into an orange/red color. However, my urine was normal. I thought that was just a side effect that some people get and some people don't, so I've never been so concern about it.
A few days ago, I had a milder pain in approximately the same area, and I almost fainted. I quickly got back onto my feet after resting for a few minutes. The pain went away, and everything was back to normal. Should I be concern about this?
