increase yer water intake.....easiest way to clear skin is to stay fully hydrated (i'm surprised yer tattoo artist didn't tell ya this, until the tat has healed) as for the spot on yer tat....ignore it...then go back and the ink touched up when it's gone
Just try not to pop it. It will leave a scar and theres nothing you can do about that because you cant cover scars. It might become a pain in the ass when it starts to itch too, just slap the tattoo when that happens and try not to scratch it while sleeping.
