My friend has these spider veins like patches on her right leg and now in 3rd trimester, will it go off after delivery?

I had faint spidery veins at the back of my knees due to my old job (stood alot, long hours). A colleague recomnended apple cider vinegar as treatment for varicose veins. And it works! Apparently, it is a natural cleanser and also improves blood flow and circulation. Apply undiluted apple cider vinegar on the skin over the varicose veins and gently massage the area. Do it every day before going to bed and again in the morning. You can also add two teaspoons of apple cider vinegar to a glass of water and stir well. Drink the concoction twice a day for one month to see positive results.
