Potential negatives of daily bonesmashing used for "pump" in school and otherwise + my own experinece with accidental bonesmash creating more bone

does laying flat on pillow help to prevent damage?

The skin there could just be hardened tissue or scar tissue. If you press the skin and move it away from the bone then itll reveal whether its skin or bone thats causing the protrusion/lump

so it's bone if i can move it?

Basically when you smash it can either bloat the bone or the skin. If you pull the skin away and the area still sticks out then its the bone that grew
