My left nipple has been pierced the EXACT same amount as my right and it still leaks, nearly every morning I have crustys that I must clean off, and a bit through out the day. Nothing excessive, though sometimes in the morning I find dried blood. I have had to go up in size on my left nipple slightly when the nipple got a bit bigger but only on one side. I have pictures that I would gladly send, however I saw no option on your website for me to attach :( I want to know is there way to get my left nipple back to regular without having to take the piercing out? Is it rejecting at a very slow rate? Will my nipple be this way forever?
You definitely do have some scar tissue formation going on there.
Do you feel like it is continuing to grow, or if it has stabilized?
I don't know if perhaps that side was pierced a little deeper than not he other one? In any case, I have some suggestions from my book for dealing with excess scar tissue (called hypertrophic scarring) and I posted it here on this website.
Also, are you wearing high quality internally threaded jewelry? If not, or if there is a nick or other issue with that bar, it may prevent the piercing from settling down.
