My DD (5) has had a series of small lumps on the top of her foot since she started walking. They are a mix of small surface bumps, much like a sting reaction, and some larger lumps on the ligament part of her feet. The larger can rub on shoes and get red.
Neither cause any pain (she would soon tell me!) but they have started spreading to up her ankle recently.
I've not sought medical attention as it's really not urgent and having no material effect on her, however I'm curious as to what is causing these, any ideas?
