Nipple piercings anyone?

Alright, so I'll be 20 soon and I've had nipple piercings for almost 2 years now. 
My left nipple is fine, but my right seems to be flakey and itchy all the time (always has been). The first year of having them the right nipple seemed like it was breaking off.. (if that makes any sense.) I tried just a small bar made for my nipple and it still doesn't seem like it wants to grow back.  Any suggestions or ... anything really??
