I've had my ears pierced for nearly 2 months now and the past couple days my right piercing has been a little sore to the touch. Its not showing any sign of infection. (Not red, not bleeding, no puss, dosen't feel hot.) But I'm not sure if I should be having any soreness after 2 months. Also, this same piercing bothered me about a month ago and I had to take it out for a couple days that time. However, my left piercing has not bothered me at all. Does anyone know what could be causing this piercing to be sore? Is it normal even after 2 months? What can I do for it?
--------------------------------------------

I've had all of my peircings for over 2 years now, the ones in my ears i've had since I was like a little girl, and sometimes the just randomly get sore.

-you may have slept on it wrong
-hair may of got stuck on it
-may not have washed all the shampoo or conditioner out of it.
etc.

Leave it alone, dont touch it and clean it in the shower.
If it doesn't get better in a week it may be infected.
