What is this mark under my nose?!

I have no idea where else to ask but... I've had this red mark in my nostril for years, it's like under the skin and I never questioned it, just covered it with makeup. Recently and as you may be able to see in this photo it's gotten quite red and inflamed, more like a blood blister. It looks like I have a cold all the time and blew my nose too hard!!! 😫
