Well, you haven't yet got it tattooed, which is a good thing. I don't know, you have me baffled, all I can think of is that you have either an allergic reaction going on, or some chemical you were exposed to at some point is responsible for making your skin growth there to become altered in its morphology. Or you're one of those reptilians. Ok, I've gone overboard on that maybe and I apologize if the rolling eyes and smile weren't visible. All kidding aside, I'd almost bet that its some kind of allergy to household or other chemicals that's been going on a long while. Think of what products you've used for a long time, and try substituting a competitor's product, for like a month in each case. Or, do a massive changeout of all chemical-laden household products. Then again, what the H do I know about anything ?
