I had a shave biopsy on my nose two weeks ago and got no post-surgery instructions from NHS at all. Now the scab has formed for more than 2 weeks and has not fallen off. Could you please tell me Is it right to keep the scab and let it fell off on its own? What should I apply on this wound? In addition, as far as I can see my leision has not been removed completely, what will be the consequence of that?Thank you!
