I have numerous bone mets.,first diagnosed in 2012. At first I had serve back pain which I tried to ignore, thinking it was from picking up my young grand children, but the pain got worse. When I was riding in our car and we hit just a small bump the pain was so severe it made me go and see my GP pretty quick. I had xrays followed by a bone scan and found out there were bone mets. In my spine and the severe pain was because it was compressing my spinal cord. My specialist said If I had left it much longer, I could have been paralyzed . So I think its a good idea to get any pain checked out and not leave it too late, just for peace of mind.
