There is something on the back of my neck.

I have something on my neck, it looks like pus and is swollen. However, there is no particular pain.

When you touch it, something like pus is inside. And then a strange smell also comes from your hand. Even though I keep washing it thoroughly, it doesn't get better.

It's been about two years since I started experiencing these symptoms. I've tried applying medication, but they don't go away. The hospital also doesn't know the exact cause.

It's just frustrating.
