A lump has formed under the skin after the wound healed.

It's so small that you can hardly see it in the picture, haha.

Recently, the staple pin was driven in too deeply, causing a wound.

I applied ointment immediately and it healed well.

Now only the white shell (?) remains.

It feels like a lump has formed under the skin where there was a wound.

There is a hard lump, and when I touch it, my hand prickles and hurts.

It hurts every time I grab something, so I'm surprised ㅠㅠ

Is the lump forming as the skin heals?

It will disappear if I just leave it, right?
