Hello. About two months ago I began having swelling in my feet and ankles, but mostly in my left foot/ankle. No pain, no discoloration, can walk/run just fine. It appeared to do this during the time of my menstrual cycle, and would come and go. This last month, the swelling remained. I went to my gyn who said it was bloating and gave me diuretics. It did not help. I then went to my internist who suggested thyroid issues (I do have a very tiny cyst on my thyroid that my doc has watched for the past two years) and venous insufficiency/reflux. My blood test to check thyroid was borderline normal, and I must retest next week. Also, my potassium levels are excellent, and my doctor does not suspect heart, kidney or liver problems. I had a Doppler ultrasound on both legs done last week, and the results were no venous reflux suspected/good circulation and no dvt. I am now being told to wear compression stockings to help with swelling. My only health issues are being overweight, poly cystic ovarian syndrome, large fibroids, large uterus, and severe cramping during menstruation. I take metformin prescribed by an endocrinologist to treat the pcos but I am not diabetic and my glucose levels are excellent. The swelling is in the ankles, foot and just above the ankle. The measurements of my legs (calf and thigh) are the same. The ankles measure 9 inches/right and 10 inches/left. I would like a second opinion. What other things could be causing the swelling in the left foot/ankle and occasional sharp pain in the calf at rest?
