I got my ear pierced in the cartilage last week, (Top the left ear) I had it done by Needle and it has a Titanium loop in it. It was fine all week barely had any pain, and it wasn't even that sensitive to touch, like if I put a sweater on and I hit it.Last night, I slept on it even though there was a little pain. Today my ear is a little red, and swollen, and there is a constant pulsing pain, its tolerable but the most I've had since its been pierced , no liquids, just swollen and red. Could this be and infection or is my ear just likely irritated because I slept on it all night?
