My husband was diagnosed with a 4x3cm cyst on the back of
his brain when they were performing a MRI
on his upper back
. He has had a constant headache for 3 months, vomiting in the middle of the night, tingling in his arms and hands, upper back pain and lower back pain. He has a herniated disk in his L4, L5 and his pain has gotten progressively worse. He thought he had more herniated disks in the top of the back but there aren't any.
