Any remedies for nose pain after blowing it so much?

Yes. The skin at the nostrils and the delicate lining inside can become very irrtated with excessive nose blowing. In general blow your nose more gently and wipe with lubricated kleenex. Steam inhalation may provide some relief. Use over the counter nasal saline spray two to three times daily for about one week. There is saline gel over the counter which is safe to apply to the nostrils.
