Good evening, after childbirth on my right leg a strong varicose vein appeared, Vascular Surgeon prescribed me tablets Flebodia, and directs me for surgery, I cannot take the pills as it is contraindicated during breastfeeding, has anyone had this or is having it, how was the situation resolved? I want to keep breastfeeding for at least a year for my baby who is 9 months old.
