8.6cm complex ovarian cyst

I had a hysterectomy 4 years ago due to endometriosis. But because of my age they left 1 ovary. I am now in so much pain. I had a scan last nov and they detected a 2cm complex cyst. I was was urgently referred and the consultants decided to do some blood tests and re scan in feb. I have now had my bloods done they all came back fine but my complex cyst has grown to 8.6 cm with a solid mass of 3cm. I have been going out of my mind all weekend with worry. I now have to wait to hear from the consultants with what the next steps are.
