This may be nasal vestibulitis, that is, chronic inflammation of the skin in the nostrils, because chronic inflammation has secretions and scabs, causing nasal discomfort. The more uncomfortable I feel, the more I want to dig with my hands. Picking the scab by hand will damage the skin and mucosa again and scab again, forming a vicious circle. In this case, you can generally apply sesame oil to your nostrils. If there is secretion, don't pick it with your hands. Before going to bed at night, apply oily eye ointment on your nose, continue to apply hot compress, take vitamin B complex orally, and cut your nails.
