About 2 years ago I went to the neurologist for debilitating migraines. I underwent an MRI and they didn't find anything but a cyst. I don't remember the name or the location I just remember the doctor said it was incidental finding and that it wasn't related to my migraines. I went through various treatments none completely getting rid of the pain and eventually I just stopped going because there wasn't any beneficial outcome. However, today I had one of the most debilitating migraines I've ever had. It concerned me. Could my migraines be related to the brain cyst? How can you tell when a cyst is growing? I just remember the doctor told me it was a cyst that probably formed while I was a fetus and that there is little chance it will grow.
