I have (what I think) are skin tags behind both knees. There is usually a cluster of them, they feel raised to the touch but don't hurt or bother me in any way.
However, we have just come back from holiday in a hot country, where I drank a lot of water each day, and the skin tags have all but disappeared 
AIBU to think the sun or hydration helped?! Can't see anything on the internet so hoping a MNetter can shed some light...
