When I was 13 years old, I complained of migraines and was sent for an MRI. During this MRI, an arachnoid cyst in the posterior fossa of my brain was found. The cyst was pea sized, but I do not recall exact measurements. Now, I am 26 and I am having more issues. They did a CT Scan and found that the cyst measured 2cm x 2cm x 3cm. I was sent to a neurologist and he was treating me for migraines. He also sent me for a MRI. The MRI measured the cyst at 3cm x 3cm x 3cm. Along with the intense migraines I ve been having, I get dizzy, see spots, faint, lose feeling in my hands and feet, and I m having memory issues. This is all random activity. The doctor told me that I could have a seizure also. He doesn t want to see me for another 6 months, but all of these symptoms are really affecting my daily life. I need advice and direction as to what I should do, please!
