I have been diagnosed with an left ovarian cyst and left kidney cyst also. The first two scans showed no change in the size of the ovarian cyst, and I was put on to the pill. Since then, the ovarian cyst has increased in size. Since my most recent scan only weeks ago, I have devoloped a lump just under my belly button that is about the size of my palm. This has been present for about 5 days. It is tender to touch and is a hard mass when I wake in the mornings. I wonder what this lump is likely to be related to. I have been also feeling more aching and naucious than usual. Any thoughts on what this lump may be due to would be greatly appreciated.
