Is a vein visible behind right ear concerning? (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.

Thanks for sending the picture. Its very common to see veins on the face and behind the ears and they are ususally seen in people who are very active and work out a lot. Usually there is nothing that you need to do to get rid of those veins but if they bother you we have had great success in treating them in office. The best way will be dtermined after looking at it, but overall these are not diseased veins. 

The vein behind your ear looks totally normal.  It is not uncommon to have veins on your face or ears that look like this.  I would leave it alone.
