Thanks for posting your query.
Shoulder blade area is supplied by C4 & 5 and narrowing may cause pain in shoulder area along with upper limb.
As such there is no correlation between narrowing of cervical space with headache.
Presence of multiple symptoms along with headache may be due to migraine
or may be due to trigeminal neuralgia
You should consult with internal medicine specialist / neurologist
and should go for thorough check up.
You should go for CT/ MRI scan brain and cervical spine
for better clarification of disease.
You should take medicines for neuropathic pain
on written prescription.
You should also consult with physiotherapist for faster recovery.
