I've been ill for a number of years but never had this symptom before. Retaining a lot of fluid in my lower legs and knees, its actually making them look distorted. I tried reducing my salt intake and fluids which worked quite successfully, but I was permanently thirsty. Have seen the doc and she is doing full blood tests including liver/kidney function, thyroid, diabetes, cholesterol etc. next week. Just hoping its nothing wrong with my heart as I've had a lot of missed beat type symptoms recently too. Without pre-emting the results, just wondering if anyone had treated this with herbs etc. Or any other useful info.
