I know being overweight is a major risk factor for varicose veins but need to find an exercise type that won't make them worse. Has anyone found that running has made their veins worse? I want to start couch to 5k but am reluctant incase running does make my veins worse. I'm going to have them lasered but not until I've lost weight. I'm hoping that losing the 3 stone I need to may even help them a bit. Any help welcome!
