Hi, Thank you for providing the brief history of you. A thorough clinical examination is advised followed by an x-ray of the upper back, cervical spine and shoulder joint. As the pain is in the back of the shoulder which is including the upper portion of the right hand, i feel you need a thorough clinical examination. As most pain and aches need to be differentiated as pain is most of the times the nerve related issue and the ache is most of the times related to the muscular issue. Also, if your doctor has diagnosed you with spondylosis, then you have cervical spine pathology for which i will advice you to under go the MRI of the cervical spine. As by understanding the soft tissues and the nerve pinching in the cervical spine we can later plan a proper treatment for better outcome score. Also, spondylosis is a ageing related issues and the medicine prescribed to you are symptomatic relief and you should continue for time framed by the doctor. Also, undergoing the physical therapy post the clinical examination and MRI will help you regain the maximum functional ability and reduce the pain as well. In my clinical practice most patients with such issues are referred to physical therapy and they respond well with 100% functional abilities. Regards Jay Indravadan Patel
