I'm suffering from painful varicose veins of the vulva and lower goin area, along with what appears to be a femoral hernia. I'm 24 weeks pregnant, wearing medial support hose and have ordered a babybellyband for added support. My doc. has also recommended icing the varicose veins in the evening. I'm concerned aobut blood clots and the veins rupturing. How can you prevent/ tell if a clot is forming?
