Hello, I have studied your case. According to your complains such kind of pain can due to compression of nerve and muscle sprain on shoulder. When such patient comes to my hospital we usually take x ray spine to see for severity of nerve compression. Another differential can be nerve compression due to disc bulge which may need MRI for confirmation. Medication like methylcobalamine with muscle relaxant and analgesic will reduce pain, you can take them consulting your treating doctor. You may consult physiotherapist for further guidance. He may start TENS ,or ultrasound which is helpful in your case. You may need to take rest for early healing. Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care Regards Dr Vaibhav
