Hi there. I have a varicose vein in my leg that I got during my first pregnancy. It hurts from time to time but hasn't been a problem. I notice now that I have a large knot on the top- it's about the size of a small grape. I know that clots here are different than DVT clots. But it's still freaking me out. Should I be worried? Call dr? Any input is appreciated. I'm a single mom pregnant with baby #2 and you ladies are absolutely my sanity savers!
