Hi
I am 33 yr. old female and I noticed a purple bruise on my lower abdomen (about 4 in. long & about 2 in. below my belly button).  It does not hurt & I did not bang myself anywhere.  I've been feeling nauseous in the last week and I have some pain on my right side below my ribs.  What could this be?  I did some research online & everything keeps leading me towards abdominal aneurysm.  I'm concerned.
