But I'm worried because it looks nothing like the other cyst I've seen. Even the doctors say it's a complex cyst. I'm attaching a photo. Has anyone ever had a cyst like this? Also I'm worried abou surgery. I've never had surgery. They told me I'll be under general anesthesia. I'm scared. I have anxiety. What should I expect? What are the steps they take on you before you are put to sleep? Will I need to be on a breathing tube? Please help. Thank you.
