thank you this information of low cerebellum .
Hi,
Posterior headache and neck pain with increasing severity may be due to cerebellar tumor(eg-glioma),blood vessels abnormality like aneurysm of vertebral or basilar artery,complete loss of blood supply to some part of cerebellum or upper cervical vertebral diseases.MRI is the ideal investigation in your case.Till that you can use tab paracetamol 500 mg ,maximum 6 times a day.
