I thought this because the bumps appear exactly on the same location where I had
pimples. The biggest bump I thought was related to a really
big pimple I had
on my nose 5 years ago. Now, I don't know if the bump was very big at first. I would think if it was big at first I would have noticed it and been conscious of it. But as the years went by, I would get some more pimples on my nose and then when they would be gone a couple of bumps. Logically, I thought the bumps were acne scars.
