There is a vein coming out from my left nostril. I'm not sure if it is one but I would like to know what it's called (Photo)

It’s important to distinguish between varicose veins and spider veins when choosing between laser therapy, sclerotherapy, and vein surgery. With two board certified vein specialists, our center uses a combination of visual examination, functional flow measurements, ultrasound, transillumination, and infrared light to map out vein networks prior to therapy. Lasers can be used to treat deep varicose vein insufficiency, vein perforators, and varicose veins. Sclerotherapy is ideal for spider veins and reticular veins. Whereas surgery is reserved for severely incompetent varicose vein segments.

The picture is not of the best quality but I believe what you are referring to is telangiectasias. These are little red veins that are common around the nose area and other parts of the face and can be treated with various laser devices quite easily with no downtime and little discomfort that lasts only seconds. While it is strictly cosmetic, if it really bothers you consider having it treated. 

There is no specific name for these veins but can be successfully treated with laser. Good luck.
