[|Human|] I was in an auto accident three weeks ago and had a 10 inch black and purple bruise on my right breast and collar bone are with hard lumps underneath.  The bruising is gone and the hard lumps are slowly going away.  However, I am now having pain and burning in my collar bone.  It seems to be getting worse.  Im wondering if it is a bruise.  Thank you.
[|AI|]  Hi. Thanks for your query and an elucidated history. It is good that the bruising is gone. The pain and the burning in the collar bone area may be due to either there is a hairline fracture for which you have to get X-ray of the area with a pointer kept on the spot of pain. Another possibility is the sensory nerves are getting entrapped into the scar tissue and giving you a typical burning sensation. This would go away on its own. IF severe, request your Doctor to give medicines for the same.
