About 4 months ago I noticed a small growth on my right shoulder and thought it might be a bone spur, no pain or discomfort so didn t worry about it. A couple of hours ago I was changing clothes and had an itch on my collar bone and was quite shocked, my collar bone on the right side has changed shape and protrudes, don t think that s the right word. The left side is more flat, the right has become rounded and sticks out significantly and the original bump on my right shoulder has grown and changed as well. I am not an alarmist and usually aren t bothered by most things but I have to admit, I m a bit freaked out.
