Don't fret overly much that your elbow is hurting - doesn't mean you've definitely damaged it as well...
The way the nerves in the arm work is a bit crap - if the nerve itself is tweaked rather than the nerve endings the brain has to interpret and guess where the hurt really is, and it's remarkably easy for this to happen because of the way the nerves go around the shoulder and out from the body.
You've probably changed your posture becaues of the hurty shoulder - which is pretty much automatic - and this can put preasure on a nerve causing pain.
Now with the way the body works and tries to repair itself you can end up with swelling caused by this nerve response. This is sometimes the case when Carpel Tunnel symptoms present - which is why cortisone injections and carple tunnel can be totally ineffective and why some people will tell you that only yoga and physio work - which wont work in the event that the carpel tunnel is genuinely damaged/inflamed...
When I tore my rotator cuff my elbow became swollen and hurt like a bastard, and my wrist felt like I'd sprained it... was wearing a braced wrist support and a neoprene elbow support... pain in my shoulder was the lesser of pains... even though I knew what had caused the damage it didn't seem the shoulder was worth paying attention - not till I had to break hard while riding the bike, then the pressure/weight on my shuolder left me in so much pain I almost fell off. A&E nurse asked me to move my arm in certain ways and it turned out my range of motion was massively impaired - was a suprise I must have been subconsciously adopting a different posture that just didn't use my arm in such a way... arm was put in sling and with the weight off my shuolder wrist and elbow stoppped hurting within a day.
There's a good book It's Not Carpel Tunnel which goes into detail about such things.
At least with a break in the shoulder there's no chance of diagnosis and they're not going to end up operating on your wrist when the damage is in the shoulder
