[Concern] My skin is itchy

I'm not sure if I should say that my skin is itchy.

It has become so uncomfortable that I need to scratch.

Even after going to the dermatology clinic, they said there was nothing special.

I received a prescription for ointment, but it doesn't seem to have any effect when I apply it.

Bug bites? The itching keeps bothering me.

I don't know why. I was just wondering if there might be something like bedding or something at home.

I tried changing everything and washing it, but it's still the same..

I can't keep scratching it, and it's really frustrating...
