I took out my half inch gauges an hour ago and my ear was really bloody and now the skin is turning black what do i so i skipped a size which was 7/16 i went 00 to 1/2

It's : It's hard to know what happened to your ear without seeing it. It is certainly concerning if your skin itself is turning black so i would suggest getting your ear checked out urgently to make sure everything is okay.

Med Eval.: I agree with dr. Lamperti. Gauging is meant to be a very gradual process. You should never skip sizes when titrating up and there should be a minimum of two weeks before another piercing stretch. Rapidly increasing sizes can lead to infection. I agree with obtaining medical evaluation.
