hello, i am 26 years old and am a healthy female, about 165lbs and 6feet 2inches, i have had varicose veins for years and was wondering if it is serious and should go to the dr if on my right knee my vein goes over it and is hot and inflamed, also there is a hard lump the size of a pea in there, as well it is painfull some days to walk. Also my same leg has gone numb about a week ago from the top of my knee to my thigh, thank you for your time...
