I seem to have a compulsive chronic need to pick my nose especially after work as I work in a care home I find my nose gets very dry. I have a sore right nostril now and using my torch on my phone can see how red it is and it appears I have ripped the skin away and something I continue to try pick is actually he outer edge of the rip ( a bit like a scab) my girlfriend thinks I m scratching away cartilage ? My left nostril isn t anything like this, is it something I should just leave alone to heal or seek further treatment
