@Kelly527 it sounds like you are definitely too close to the top of the skin go a little deeper you will definitely feel the difference,they definitely will slide in much easier when you are in the right plane.also don't use old threads they do have a shelf life.especially after you have opened the pack from what I can remember reading you have about a week to use them. Try a digger gauge needle and get them from a reputable dealer not from eBay. And use them as soon as you get them.
@Angela80 actually I just saw a video on this problem from a well-known California doctor he's on YouTube I think his name is rajya .just look up threads you will find him he has black hair he looks like he's stuck in the '70s. Go to his playlist and look under PDO threads. He has a video on why some threads bunch up. Basically it might be the thread itself do you use them straight away after you have opened the pack they do have a shelf life.are you getting them from a reputable source or are you buying them from eBay. He warns about the quality of threads.
just a reminder when you put them in they should glide in easily if you're in the right plane it should not feel like a needle is going all the way into your skin. Slightly uncomfortable but definitely not a pinching needle sensation.
@Angela80 are you sure you are inserting them in the right plane.
How frustrating for you.maybe go and get a couple done with an expert and then you can pick their brain and see what happens when they put it in. Just to make sure it's not you or your skin rejecting them.
