M.W.
While I have vv myself, as a midwife, I've learned a few things since that I wish I knew when I was pregnant! I used compression panyhose (Yuck, esp in the summer!) Witch Hazel compresses, Vit E (d-alpha, not dl-alpha) and elevating the foot of my bed so my feet were higher than my heart all helped somewhat. Never had the resources for the brace you are refering to, so don't have any feedback on that aspect, sorry.
Since then, I have learned that Noni juice, and several herbal remedies also help a lot a lot more to aliviate the pain & severity.
vv are always worse during pregnancy, because that's when your blood volume expands. While the vv don't get "cured" w/o surgery, when the blood volume returns to normal, the pain disappears... until next pregnancy that is. :)
