My 2 year old son has this on his big toe, it first showed up a few days ago and I assumed it was a blister and that his shoes were getting too small and he just needed new shoes, I also checked for any stones or anything in his recently worn shoes and there's nothing.
It disappeared for a couple of days but has come back today and he hasn't worn any shoes as we've not been out in the last 2 days. It isn't hot to the touch, isn't leaking anything, he's walking normally and allows me to touch it so I don't think it's causing him discomfort.
I also suspected a splinter but surely he'd show some discomfort and I've shined a torch against it and can't see anything in the skin.
I'm going to take him to the pharmacy tomorrow and hopefully they'll be able to take a look at it and give some advice.
Has anyone else had this? Do I need to take him to the doctors?
