If u have a line on your nose does it mean that u have allergies?

Nasal Line: If the "allergic salute" (running your palm up your nose bc it runs all the time) is what is happening, some people can develop a line across the nose. Could be allergies. Get it evaluated.

Allergic nasal creas: This is the transverse nasal crease across the lower third of the nose where the soft cartilage meets the rigid bony bridge. This a frequent finding in allergic patients that is the result of the continual rubbing and pushing of the tip of the nose to relieve itching.
