you have a problem in the cranio-vertebral
junction, the place where your skull meets the spine and it has been impinging on your crossing fibers of brain coming to spinal cord; yes, you need a repeat MRI
including brain as well cranio-vertebral junction and after that if you can post the images or consult neurosurgeon, it can be of much use to you, to get a relief. Do not try all the non-medical methods of massage
or others- it will rather aggravate!
