I've done a project on something that sounds a lot like that, but I'm not a doctor, so you might want to consult your doctor so he can take note of this and see if anything is wrong, my project was on a deadly disease.  But it could even be like a rash or something.

Ohh a bunch of my friends have phones with a sliding out qwerty keyboard, or a flip phone and tracfone . Those phones are good for 12 year olds because they are low priced and not to complicated to figure out.  Lg neon go is kinda cool, or the pantech matrix.
