I have had pain in my shoulder for 3 days - yesterday after helping my husband stack wood, my pain was worse than ever. By this morning, I have a very sore lump on the colarbone where it meets the sternum and swelling immediately north and south of the lump...what do you think it is?
Hello, It looks from your details that it may be trauma induced inflammation of joint near sternum bone. You should do rest, avoid straining your affected shoulder area. Take a good analgesic like Advil for relief. Take care. Hope I have answered your question. Let me know if I can assist you further.
