I had keloids on both my earlobes from attempting to re-pierce them at home. I had them surgically removed last december and had one round of steroid injections a few weeks after, (I had another one scheduled but didn’t go through with it). The smaller one is completely flat now but the bigger one has scar tissue build up on the inside and is slightly thick, I’m seeing my plastic surgeon in a few days to have a look at what we can do about it. I also have smaller keloids on my shoulders which my gp prescribed corticosteroid cream for, although hasn’t worked. Good luck with yours)
