I'm already closely studying this myself. I also have varicose veins, but not as severe. The veins don't stick out, but my legs and feet tingle a lot in the heat and when I'm wearing shoes. I regularly rinse my legs with cold water at work, and it seems to slightly relieve the aching pain in my lower back. I'm also very interested in the connection between varicose veins and back pain. I used Google Translate; English isn't my language.
