D2 definitely needs a pair of really effective compression stockings! The many "perks" of being a teacher is the long hours of standing on daily basis. She was walking in front on me when I noticed the "almost" angry blue-green veins at the back of her left knee. D1 has noticed these too and had recommended that D2 should have an injection of some sort directly on the vein to arrest further varicose vein development. D1 said that enlarged varicose veins could be painful later on. Tomorrow, D2 is set to source for affordable compression stockings!
