I am attaching my cervical MRI report ..i am having vertigo..it happened once 5 month ago and now again when i have started my physiotherapy.. physiotherapist told me it's bcoz of your neck problem..i want to ask what causes cervical vertigo..is there some artery compression or nerve compression?? And can this compression result into some permanent loss of blood flow? I feel vertigo mostly while lying on bed..also there is tinnitus in ear..
