Hi All,After 2 years of working on my feet for 12hr shifts, I've developed spider veins throughout my thighs and have noticed a varicose vein forming behind a knee. I want to buy compression hose but don't know what gradient is best: 15-20mmHG, 20-30mmHG, or 30-40mmHG? The problem for me is that I'm only 4'11'' and 95lbs. All the 15-20mmHG hoses I've found online only come in sizes S,M,L. I'm afraid the S will be a bit too big and the hose will not work properly. I've found petite sizes in the 30-40mmHG but can too much compression do more damage than good?Does anyone know what compression gradient is best for preventing spider and varicose veins?Do any 15-20mmHG or 20-30mmHG come in petite(short) sizes?What type of exercise is best? Cardiac or weight lifting?Anything else I can do to prevent or treat the spider & varicose veins (other than the laser surgery)?What type of doctor usually treats this problem? Dermatology? Vascular?Thanks so much for your help!
