Does anyone else have a problem with a lot of cysts? I've had them on my hands and feet, my neck and chest. Now I found out that I have them in my sinus cavities as well, causing a lot of pain and pressure. I don't know if it is the Crohn's, the medications or that I'm just prone to them, but they are annoying. Many times they get infected, too, so then they have to be removed surgically.
