hello dr. I am a 67 year old female. 171 cm 110 kg. On Tenbloka 50mg, Eltroxin 0,15mg, Cilift and Premarin (Vaginal cream) Hysterectomy 1980. Had my first varicose vein operation (stripped from groin to ankle) +/- 30 years ago. Since then had about 4 or 5 more operations and injections. My problem is still there and getting worse. Thick veins all over my calves and feet, especially behind my left knee. The blood circulation in my legs is not wonderful, is it advisable to have another operation?
