DD (13) has developed this hard knobbly lump by her big toe. It’s a bit like a bunion, but it’s not on the side of her foot, and google seems to say bunions are always on the side.
It’s not filled with liquid/pus; it’s hard like bone, but you can wiggle it about a bit. She says it doesn’t really hurt but can be slightly sore sometimes.
Any idea what it is? Any reason to see the GP if it’s not bothering her too much?
