Where my ear piercing is at hand is a lump resembling a blind pimple or a cyst. How can i get hold of rid of it?

I havent been wearing any strange earings and i try to pass my ears a break and swap sterling sliver and surgeical steel ones. I never borrow other peoples earings and the lump isnt noticable it just hurts rather bit when you touch it. Any ideas? It probably is blotch tissue. Whenever the body receives a trauma (which piercing is) or is exposed to a foreign body (like earrings) one of the ways it responds as it heal is to form scar tissue at the site. As long as the nouns isn't red, warm to the touch, swollen, tight all the time and/or draining pus (all of which could scrounging an infection or allergy) then it is probably defacement tissue which won't go away, but is not adverse.
its an infection. Remove the earring let it restore to health up and use gold earrings if you establish to pierce it again.
