Im 29, female and I had my first seizure 2 months ago and the doctors didnt prescribe anything coz it was the first time. They said if i get another,they ll give me epilepsy medication. My diagnosis was a 2.6cm x0.6cm arachnoid cyst and abnormal brain waves after the sleep deprivation test. Also low iron, high white cell count and high creatine. I read cysts are either left alone or if they keep causing issues, they need to be operated and drained. So why dont my doctors say anything about surgery? I also have PCOS. Is my cyst considered large or small? And how serious is it exactly? What should i know? I never had any experience with seizures and cysts before,i have always been quite healthy, so im kinds freaking out now.
