Please take a look at the scars and pain in the affected area.

It was cut and twisted around the chest area below the collarbone.

Since it's a melting thread, I haven't heard anything else about showering the day after tying it.

But I was still worried, so I applied red ointment and put a wet bandage on it for about two days and then took it off.

But later on, it became a little bumpy like this

The scar doesn't matter, but when this protruding part slightly brushes against my clothes, it stings like there's a sharp pencil lead stuck inside.

Even if I lightly brush it with my hand, the part where the arrow is pointed stings the most, and the part that sticks out slightly on the left also stings. Why is that?
