Every so often, my third and fourth toe on each of my foot splits open. It's always along the crease on the underside of my toe (the bit where your toe folds over). It's always the third toe on my left foot and the fourth toe on my right foot.
It's just done it again (I woke up this morning and my toe on my left foot had split open all along the crease). There's no blood or anything, no sign of a cut, it's just split open and it's like raw flesh. It's the crease that connects the toe to my foot, so naturally as I walked it opened it up more and it's gaping open. It's still not bleeding, but it is oozing a bit. I've covered it in antiseptic and a plaster to try and prevent anything from getting into it and making it worse. It's very painful at the moment. I've also got a smaller one on the fourth toe of my right foot, in the second crease which isn't as painful, but it's still only just appeared as well.
This happens all the time. Every few weeks or so they open up, always on the same toes. Does anyone know what might be causing it? They normally clear up fairly quickly (though the one I've got at the moment is the most painful and inflamed I've ever had), and as I work full time by the time I think to make a doctor's appointment they've gone. Google is only bringing up results related to babies, and as far as I'm aware I haven't been one of those in a while.
Ta in advance. I've kept it anon because it's a tad gross!
