Laura, I'm so sorry you're struggling so. I agree w/ Wylee and Heidi ..you definitely need to get it checked out! I had one revision because I had a hard lump in my side..it hurt and moved when I pushed on it. They didn't see anything at first, but did another scan a month or so later and found out my catheter had come undone. It turned into a huge knot. My headaches were excruciating, but the surgery was simple and fixed it. As you can see from just these few posts, it could be a lot of things. I would definitely be concerned about your history of cysts and follow up w/ your surgeon! as soon as possible.
Good luck, and keep us posted!!!
Julie
