I have for the past year or so had a spot on my bicep that swells up...and has bruised for no apparent reason in the past. No one (doc, PT, MT) has been able to explain this other than that it is prob a muscle spasm...You can see the 'bump' most of the time...when it flares up it gets worse.

I know once I get swelling I have to take it easy...I haven't noticed swelling in my scar area though (collar bone) in quite some time...so I really can't add there. Sorry!
