I doubt that the hemangioma in the bone is the cause of your pain. This is becoming a common finding on many spine MRIs.
I would consult with a neuro/spine specialist and have a thorough spine and neurological exam done.
You could benefit from aquatherapy and relaxation techniques.

Hi,sorry to know it,my opinion as fellow:
The pre-degenerative signs at C2 - C3 and straightening of the cervical spine are due to soft tissue injury (Probable whiplash),this injury can lead to chronic neck , upper back pain and muscle spasm.
So atypical hemangioma or a mildly desicated disk are not the cause of your chronic neck pain.
Carry on physio treatment,plus deep and intensive acupuncture to relive inflammation and keep moving...
Good luck!
