I have an arachnoid cyst that measures a 3.6 cm x 2.25 x 2.75. I m having symptoms of intense and Isaiah headaches pressure in the top of my head and neck aches insomnia freezing blood pressure going high then low heart rate dropping down to 35. But I was sent home because they said they didn t think these were symptoms of anything. I m in the state of Florida now the back in 2001 had to have surgery because the arachnoid cyst was wrapped around my brainstem shutting down my normal bodily functions. I m feeling worse than I did then. I have bad health insurance and think that is why they sent me home. Please Help!!
