I've had 2 holes in each lobe & 1 cartilage piercing in the left ear for decades. I've been considering getting a second cartilage piercing in the left ear but just can't decide. It's not high on my priority list right now. I never had any trouble with the first one & it didn't hurt. It healed well & I was sleeping on that side within a week. I didn't change the earring until about 3 months though to make sure it was fully healed.
