My Daughter Had A Mir Of The Brain Today That

My daughter had a Mir of the brain today that showed a white spot on her cerebellum. Doctor asked if she had any rashes. She has 2 spots of psoriasis. She has head pain which I think is sinus problems, tooth pain from an agrivating tooth. I heard rashes can be from auto immune disease. She had melanoma removed last year on her arm. It did not spread. Her brother has Tmj and has a white spot on his brain. They are watching his. He is 35. She is 32. She thinks she has vertigo. She very dizzy and taking allergy mess and amoxicillin. What do you think?
