I'm 39 - I guess it's about a quarter of an inch long - the edges sort of fade out and there is no itching or pain.
Ok - thank you for your feedback. Is it possible that it could be similar to a blood blister also? (after it has popped though - b/c it is flat) I thought it developed possibly b/c I had been on my feet for the whole day...the day before I noticed it and I was wearing high heels - so there was a lot of pressure on the ball of my foot.
What is - seborrheic keratosis? I can google it too - if you don't want to explain.
Thanks for your help!
