my GP doesn't do them, but if you find one who does it'll just be with liquid nitrogen as I recall; again it may take a week before it drops off. Some people just cut them off with scissors, but I wouldn't.
I have 15 -20 where my bra rubs against my skin. Probably would be possible to get my sister to ties something around the larger ones but most of them are small. The dental floss thing sounds painful.....has anyone tried it?
With that many I'd get them removed professionally. If your GP won't oblige pay privately if that's feasible. That's what my mum did but she was with BUPA.
My GP got rid of mine. Snipped off with sterile surgical scissors, then a small dressing put over the spot. I had 9, GP did 3 at a time over 3 appointments. No pain, very tiny blood loss just a spot on the dressing.
