Serious pain below right shoulder blade, pain comes and goes, do not feel it laying down. no pain in right abdomen, have an appetite, also have numbness in arm and fingers. is the pain organ related or spine?

Suggest you see a neurologist or orthopedic surgeon. Some causes include issues with long thoracic nerve, dorsal scapular nerve, cervical radiculopathy, or notalgia paresthetica, but shoulder joint problems involving rotator cuff, may be considered. Be proactive and uncover etiology.

Yes, you have radiculopathy due to nerve impingement, likely due to cervical spine disease such as herniated disc, bone spur, etc. The condition is usually self limited but it may recur or worsen, physical therapy may be helpful at times. You should see your family doctor. MRI of the cervical spines will pinpoint the cause and the prognosis.
