I am a 39 year old female. I am usually in very good health. I've been having some abdominal pains for the past week, mostly lower abdominal. Sometimes sharp pains, sometimes just a dull pain. For the last month my lower abdomen has been rock hard to the touch, the size of a 4" round size, in the area above my naval, but I hadn't experience pain until last week. This morning I woke up with a soreness in my lower right side, about 2 inches above my hip bone. It doesn't hurt unless I press it, when I do it is very tender to the touch. Any ideas what this could be?
