I have a 8 cm ( could have grown ) demoid cyst on my ovary. Waiting for op. About 4 weeks ago , it began with pain when taking sharp intakes of breath. It then resulted in me doubling over with pain that pain killers wouldn't touch. Also extreme sickness I say pain more of a period pain x 2000. I have had a couple of these really bad episodes since. It hasn't twisted I have had that checked. In between these episodes , I feel very unwell : sick , sometime headaches and just generally shit. I am really hoping this is all to do with the cyst, but what are other peoples experiences ? They don't think it is cancerous and have had blood tests
