ok well, when I am sitting my leg is fine unless I have it bent and under me. but now lately, when I go grocery shopping, and walking around..my leg falls asleep. it falls asleep like 10 or 20 minutes after Im walking around. it frightens me because Ive heard it may be poor circulation and sometimes a clot can form and if a clot gets to you heart or brain.. you are dead! please help! thanks in advanced!
