Hi, I deeply understand your concern for your health. Since you have mentioned that you have neck pain and shoulder pain, its most probably a muscle spasm as told by the doctor. - you can take the medications and do stretching exercises for neck available easily online. - when you wake up lie on your chest then using two hand lift yourself up, in a arc like position and then lie down slowly Repeat his at least ten times daily. This will surely relieve back pain. no symptom is less to be afraid, the doctor shall always be there only to allay your concerns. Hope I have answered your query. Let me know if I can assist you further. Best regards, Dr. Suhas Chauhan
