After spending the last couple of days in hospital with severe headaches, high blood pressure and lots of spots before my eyes, a CT scan (which I was originally told came back completely clear) apparently shows an arachnoid cyst on my brain. The consultant was sure it wasnt connected to my symptoms (they are saying it's all essentially just stress) and that it wasn't anything at all to worry about but now all I can think about is the fact that there is a cyst on my brain! Has anyone any experience of these please?
