Mine didnt hurt either, it was just a hard bump., maybe a calcium build up
It could be a cyst like a bone spur, is it hard ..I had one on the bottom of my foot and them another on the palm of my hand ..I read and interesting atrticle that said regular massage worked to disperse it.So I did massage a few times a day on my foot and after a few months it did go away .I also did the same on the palm of my hand .again its has gone .try it but you have to massage regularly .
