The photo is very small, only 6kb, could you send me the big pic to CONTACT.
But this looks very like Tietze's syndrome to me. Is that lump warm and swollen? It looks it. Is the lump tender?
When Tietze affects the sterno-clavicular joint it often affects the brachial plexus, hence the radiation down your arm. Ask your doctor to do Adson's test on you.
It certainly doesn't look like a muscular problem, though the scalene muscles may be affected.
Start by icing the joint twice a day, and see if you can find a chiropractor who knows something about Tietze's syndrome. The treatment is very specific - it happens to be something I'm interested in, but you may have to look around to find a chiro who knows how to treat it. Medication is not likely to help.
I hope this has contributed.
NB. Send me the full size pic.
