Hi, Iam A Male 70 Years Of Age With A

Hi, Iam a male 70 years of age with a good health. For the last 4 months I been experiencing a pain going from the top of my right shoulder to the end of my fingers. The pain comes every 15 to 20 minutes and then goes away. This is ongoing for the last 4 months. My doctor did an X-ray of the arm and said that it was ok. However, the pain is still here. Do you have any advice. Thank you Luis.
