Question: Is your skin concern shingles or a skin disease?

It has been itching continuously for a long time. It seems to have lasted for several months. I keep scratching repeatedly because of the itching. Since a scab formed like this, I was worried it might be shingles. It has been several months since this area started itching persistently while I was walking. I thought it would get better after some time, but the itching continues repetitively, and this condition keeps developing on my skin. The itching and problem keep occurring only in this specific area, and I am really curious about the cause and reason for this.
