I have a hard mass on my lower left side near my abdomen. It is painful, and not long aching pain it's sharp sudden pain. I had an ultra sound and they told me I have a small cyst on my ovary on that side, however if it's a small cyst how can I feel a bump on the surface considering that my ovaries are in my abdominal cavity? Also there is a little discoloration in my skin. The alarming factor for me is that the bump tends to come and go. Of course with my luck the day I had my doctors appointment the bump decided to go. I'm not sure if maybe I have a hernia but I don't know what to do at this point.
