Hi dr, I am having perodic itching issue. It comes once in while in day but it increases when i go for long evening walk. Itching is mostly on outside anus area and tittle inside. When i itch or wash anus then this itching gets reduce but not vanish. It gets nornal when i sit 30 40 min after walk. I am 98kg, 35year old guy. Have prediabatic and mild lipid increase. I walk 6 7km daily evening since last 2 years. My food habbit are mix of veg and non veg. I have stopped taking outside fast or a y food since last 1 month. What could be cause of this itching and how can i handle this?? Please suggest.
