Pain in lower left quadrant.
I'm a 20 year old male that has good health. When i was laying in bed about 6 months ago I noticed a lump in my lower left quadrant. It hurts when I apply pressure or sometimes with body movements when playing a sport or stretching. The pain is always localized in the area of the lump. Never to my back or up or down. Most of the time it requires direct pressure though. It seems to not have changed over the past 6 months. All of my blood work is normal and I also have a normal urinalysis. Any ideas as to what could be wrong with me? (Also my grandmother passed away of colon cancer when I was about 2.)
