What is this on his toe?

[kbx201]

Brown groove, noticed 2 weeks ago. Been waiting to see if it went or changed, still the same. Phoning GP on Monday but anyone got any idea?

I'd say he dropped something on it. I'm not sure it's worth a gp visit unless he's limping or it's annoying him.

Do you mean the tiny brown discolouration on the toe nail??
Looks like it had a little bang?
Can’t see anything here that I’d be bothering the gp about.

As above -it looks like a tiny bruise where he's stubbed his toe or dropped something on it.

It doesn't need to be seen by a GP unless it is stopping or affecting his ability to walk
