So for couple of years, I have been getting these itchy spots randomly. First I thought it was some mosquito bites, so I tried not to scratch it, which was hard because it is extremely itchy. However, the spots started building up pus bubbles and eventually pops. It hardens up and turns into scabs but the itchiness is still there.
I get new spots throughout the years, with the same itchiness, pus, scabs. Sometimes, when the spots eventually heals (which takes couple of months), it comes back. I saw a doctor because of this, and all she said was that it might be an allergic reaction to something and gave me a prescription for hydrocortisone cream. This cream helps a lot and heals it faster, but it doesn't make it disappear completely. What should I do to find out what exactly it is?
