I am 19 years old, male.
Yesterday I woke up with a slight pain in my lower abdomen that gradually got worse throughout the day. By night it was pretty bad, enough to wake me up in the night multiple times. I went to the doctor today described the symptoms which are; dull, achy pain, with some sharp pains. Doing things like walking, running, jumping, and taking steps down hurt. The area is painful to the touch, quite painful actually. The are looks slightly swollen. Its right under my "belly" maybe 4 inches from my belly button, but the pain can radiate all across the area and even up to my upper abdomen. I don't have any other symptoms like vomiting or fever. Also, when I lay down the pain will shift with my position.
The doctor said that if it was appendicitis I would already know it was. She had a urine sample done which came back with a trace amount of white blood cells in it, she told me that male urine shouldn't have any and she sent it to check for Urinary Tract Infection. But from what I've read it doesn't seem a URI is that painful to the touch and I don't many of the usual symptoms with it. She also suggested STDS, but I highly doubt these. She also said it was a very trace amount of white blood cells.
If it isn't URI or an STD what could it be? How worried should I do? When should I start to get worried, if ever?
I apologize for the long message but it seems like an unusual place to have pain and felt it needed explaining.
