I have been experiencing 4+ edema in my lower legs with heaviness and achy type pain. Only co-morbidity is a history of thyroid CA that was depleted by I-131 in 2005. I currently take Armor thyroid, celexa, nexium, vitamin D. I am a pack a day smoker since age 18. I endulge in a cocktail most evenings. My BP has always been on the low side of normal (90 to 120 over 50 to 80). I am not diabetic. My famlial cholesterol is borderline. Family history of CVA, HTN, DM, high cholesterol, MI, and my father passed from lung/heart issues. My mother also has early stage alzheimers. Why I am I having this edema???
