2 long blue veins running parallel down my nose that pop out? How can it be treated?

Depending on their side and depth the options would be either Laser or sclerotherapy. Evaluation by your doctor is the best way to proceed. 

First recommend. Consultation to evaluate completely. If these are smaller spider veins, a laser treatment would be perfect and one treatment should do it and price average $200 for 2  small veins on nose.
If larger, sclerotherapy is likely your very best option. Pricing will vary. And for larger veins, more than 1 treatment may be needed.
Either treatment chosen and if smaller or larger, this can be done safely and relatively quickly for you.
Best of luck,
Dr. Amy
