All the time! Everwhere! And they are not small. The only way I can get them to go down is by putting a bit of the steroid lotion and leaving it there until it goes away. Not my preferred method but these things itch!
I also just downloaded Miitomo and I love it. If you don't have it already you should check it out, who doesn't love a mini version of themselves? So I'll leave you with some fun photos. :D
