Hi, I had gone through your question and understand your concerns, If I were your treating Doctor for this case, I would ask you to do MRI cervical spine to assess any bony abnormality or disc herniation which may cause articular pain in your left arm. Also, I advise you to receive the following medications:-Muscle relaxant as Tizanidine -Pregabalin 150 mg once before sleep to improve the electric shock sensation.
