Can anyone advise please? I have a bony lump on the back left side of my scalp. I've had it for years but lately I've been more aware of it. I went to the doctors for reassurance and she is sending me for an ultrasound. She said as it feels bony it might not show so I would then need to move to the next step. She said of I've had it for ages then that's not much to worry about unless its changed. I feel its changed but simply because I can feel it more if that makes sense? Does anyone know what it could be? I am really quite anxious
