My sister has migraine headaches, numbness in the upper body (paralzyed one time) blurred - crossing vision, electrical like shocks in the back of the head. She had her thyroid out on meds synthrix, had spine surgery of the upper neck, hysterectomy, and carpel tunner surgery. She was just diagnosed with a benign (most likely) brain tumor (back bottom right) Stanford said it appears to be slow growing and benign - recheck in 6mths. Compared an mri from Nov and a contract mri from August. Dr at Stanford (neurosurgeon) said the tumor due to location is most likely not the reason for the headaches, numbness and weird vision. She lowered her synthrex and it helped a little - she thinks. She is going to go see an Opthomologist - Neurologist at Stanford. Do you have any ideas? Linda
