What causes boils to form? Please tell me the treatment methods.

I often get boils frequently, so I am really worried.

This time, it has become so large. Actually, until now, it was a boil.

Even if I leave it alone, it just goes away on its own, but this time there's inflammation.

Maybe because it's swollen, my surroundings hurt... I got a prescription at the pharmacy.

I'm taking antibiotics, but do I really need to have it torn?

I'm waiting for it to disappear on its own... and I went to the hospital because I had a boil.

I haven't been there before... where should I go?

I'm not sure whether I should go to surgery or orthopedics.

I'm really suffering because of the boil.
