i am a 64 year old woman, 155lbs, with a vibrating femoral artery for the past 3 days (right side), off and on. i don t have leg pain and I don t have leg pain when I walk. i have had for a couple of months before this, but not now, burning in the back of both upper legs from sitting too much I thought. I;m headed off on vacation on tuesday for 3+ weeks.
