Ouch! Meantime I suggest, painkillers so you don't make it worse by holding your arm stiff, plus alternating ice and heat, plus gentle movements.
Are you already seeing a Physiotherapist..? If not I'd go with one of them first, before the orthopedic surgeon... 'cos the clue is in the name "surgeon"... guess what they love to do..? OK as a last resort, but the physio will try and help you heal without cutting if at all possible.
