Probably best to get your doctor to remove them. I had one , and read that you could tie thread around it's base and it would fall off after a few days. Feck that, after 3-4 days I was in pain every time something touched it, and it was on my back along the waistline. I had a can of wart freeze, so I froze the tag as much as I could and then with the aid of a mirror I eventually cut it off with a pair of scissors. Had visions of me passing out in the bathroom with blood pissing out and someone calling an ambulance
, thankfully , it didn't come to that. On the up side , it never came back
