hi, thank you for providing a brief history of you. since you mentioned you had severe fracture of the humerus and it was treated with surgery. The procedure consumed some screws and metal plates. I have to stop here to ask you a question. were you advised to undergo physical therapy post surgery? as physical therapist will help you regain the shoulder movements and strength in the muscle as well around the shoulder girdle muscles. coming next to you neck region , since this area was also operated and disc is replaced, were you advised physical therapy even after this surgery? now coming to the current symptoms as to look into. For the pain part the physician has done all the possible ways to help you. He has been really good to deal with your injury and symptoms. I appreciate it. let s look into how can we more look forward to help you without any major complications. I recommend you to take an x-ray and figure out the shoulder and neck region bony alignment. next thing to look forward is to relax the muscle area. for that you can use hot water fermentation as it will provide a vasodilation effect and relaxation to the skeletal muscle. also to consider is slow stroking massage which will help to soothen the muscle. now come to the strength part for which you may need to take help from a qualified physiotherapist. the physiotherapist will have the scientific approach towards you. Trying physiotherapy will add on the gradual increase in the strength and which will later on reduce the pain for you. ofcourse for no doubt physiotherapy is a long and time consuming process, but to be honest is that all the possible way the physician is trying to help you. with the addition of a physiotherapy to your treatment plan will help the medicines work better. why exercise even in the situation of pain I am advising. Since medicine acts as a supportive therapy for the body, the body even needs the good metabolism and immune system to allow the benefits of medicine to happen. with exercise your metabolism will improve, oxygen carrying capacity of the blood will also improve, which will overall allow the muscle to get the strength and even the medicine will be able to help the symptoms to lower . with the grace of God I further recommend you to do physiotherapy and a good health in future.
