12 years ago, I was diagnosed with a small arachnoid cyst on my left side at age 16. I had been having nocturnal seizures for some time. I was taking Dilantin. But stopped taking it after I got married. Seizures have stopped, as far as I know.
Every so often, I experience pressure on one side of my head. Sometimes, I am extremely fatigued. Recently, I have notice pressure behind my left eye. Could this be allergies (head congestion)? I also have a strange sensation in my outer ear. Like it's asleep, minus the numbness.
My questions are, should I see a doctor? Should I have another MRI done? Can arachnoid cysts change in size?
