In 1995 i started having migraines i was in my 20s and had never had a migraine before. A CAT scan was done and then an MRI. I was diagnosed with and Arachnoid cyst, at the time the DR s told me it was no big deal and I was fine. Lately I have noticed I m having more headaches. Like my head is in a vice, more migraines, floaties in my vision and trouble focusing my eyes, and more issues with hearing things. I m also having more problems with my memory and some time I ve got what needs to be called impaired judgment. Could the cyst by growing and starting to cause more issues?
