Hi, I value your concern regarding the symptoms. I have gone through your symptoms, and in my opinion normally clavicle do not require surgery, in your case now it is in a state of non union, the burning sensation could be due to damage to your skin nerves for the incision to fix it or there could be secondary brachial plexus roots compression, you will need to consult a Hand surgeon to get clear on this, and do not be over obsessed by your clavicle, even if it dosent unite if its not hurting the skin, you can be fine but for lifting heavy weight. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health. Special note- Any medication prescribed needs to be taken after consultation with your personal doctor only.
