Hello All, I was told I have an arachnoid cyst on my brain that is pushing the pituitary to the left. This was said after 4 MRIs. Then the NS,N,Endo all just quit saying anything. THey did not say I needed any help or did not need any help. I have extreeme headaches,backaches,swelling of the hands, have lost most of vision of right eye. I have other symptoms but ---Should I look for a different Dr? Do I need a pituitary Dr. or a new NS that knows about arachnoid cyst? I need advice quickly.
