Because you mention the pain in the right shoulder, right below or around the shoulder blade, this could be a symptom of a herniated nucleos pulposus, (HNP) Herniated disk in your cervical vertebrae.
Depending on where the numbness and tingling radiates to in your fingers, is it into your thumb and index finger or does it include the the pinky finger?
Make an appointment with your doc and ask for a Cervical MRI, you may find you have a C6-C7 herniation.
