Hi,we think that my son has a slight ingrown toenail,he washed his toe and after he'd washed his toe it started to leak yellow discharge from the side of his toe,any ideas?

That could be a sign of infection, so have it seen. Sometimes podiatrists are more skilled at handling the ingrown nail.

Yes ingrown toenails can be very serious, and need to be removed properly. I would agree that a podiatrist would be the route to go.
