I think I have a pimple on my skin.

I kept scratching my skin because it was constantly itchy. The symptoms started about a month ago. Still, each time I thought it would get better by applying ointments like Glickor or Ceresone. However, these bumps have not gone away for several months now, and they remain the same. I don't understand why the skin issues haven't disappeared despite applying ointments and trying to heal. So, I stopped by the pharmacy to buy more ointments for this treatment, and I also used the ointment recommended by the pharmacist. But there was no significant improvement. Therefore, I decided to visit a private clinic. I applied ointments and received treatment at the private clinic, but I still can't understand why it hasn't healed.
