I had them when I was like 10 years old.I don't remeber any pain.We thought it was a rug burn.My Mom took me to the doctors and she gave me some pills and this stuff to soak it with.It cleared up with in two weeks.I have a scar where it was but no lasting nerve damage.I've alway wondered if they would come back.You can get them anytime.So far then never came back.
I feel for you.I wish I could remeber more but it was so long ago.
