I had a piercing in my ear which the Holistic doctor who took my filling out said take it out and let it heal! He did muscle testing and said you have a hole in you somewhere! When he found out where it was he got excited and said take it out and let it heal! How did an earring mess me up as he said it did? I don't know but he seemed very serious about it and said it has done damage.
I guess holes in your body are not good, it can throw off balance I guess and mess you up worse, apparently my earrings did just that according to his muscle test. He was very thorough.
