I'm 29, have been on birth control pills for 10 years, and switched to Yasmin about 2 years ago. I a small varicose vein in my right within 2 months of switching, but didn't think a relationship between my vasculature and the pill existed. I can now trace the entire vein from my right hip to my ankle. In the 2 years since starting Yasmin, my ankles and lower legs swelled heavily...but at very random times. It often began at the start of the 7-day sugar pill regime and finished by the time I started a new pack. I assumed that the estrogen withdrawal going into the sugar pills was too much for my body to handle and that the diuretic effects of Yasmin were obviously absent during that time. I also noticed leg cramping, heart palpitations, and I started waking up in the occasional hot sweat in a drenched bed. So, after making sure that my heart and kidneys were healthy, my gynecologist prescribed continuous hormone Yasmin and claimed it as the "ultimate solution". For 4 months, I have skipped the sugar pills for each pack and started new packages immediately. I have not had a period since, and the edema has continued (still at random) and has become exponentially worse. In the last few weeks alone, the vein in my right leg has become massive, my legs are so distended by the end of the days on which they swellI that I can't fit into pants which are otherwise loose, I am noticing other large veins "surfacing", little veins are breaking everywhere, and I can now see most of the blood vessels beneath the skin in both legs. My primary care physician told me I have chronic venous insufficiency...a diagnosis I'm not okay with. I'm very worried...the changes and ensuing damage have happened way too quickly to be venous insufficiency. I am going to ween myself off of the pill, but don't know what the next step should be. Endocrinologist? Another OB/GYN? Anyone have ideas or similar experiences to share....
