Hi, 

Not exactly the same experience as you but I just wanted to share my story so far. I had a chest xray at A and E back in Aug following a viral infection which luckily was all clear. However, 3 weeks later I had a phone call from the hospital saying that on the xray they had spotted something on my upper right arm. I was asked to go and meet a consultant who told me that I have a mass/tumour on the bone in my upper right arm which came as a total shock. He did say that he thought it was more than likely to be benign but I had to go for an mri scan to investigate further. The scan was a week ago and I am waiting for the results.

For the last few months I have had some pain in my arm on and off and initially didn't think anything of it but it has got a bit worse, mostly just a dull ache but quite discomforting so I keep thinking the worst and that it must be growing! I can feel my tumour under the skin, about 2-3cm too. 

Really hope that you are doing ok.
