Awhile back I bought an ear piercing kit from walmart and ended up piercing my ears twice more, not in the cartilage though, now I have a row of three earrings on each of my ears. Problem is though, the studs from walmart are pretty cruddy, as in they aren't the best studs around... and it has been impossible for me to get them out, the back refuses to come loose. Has anyone ever had this problem? Anybody have any tips to remove them? Thanks!
