I have always had slim legs but in the last year both my knees have become very large and swollen. I have now noticed that patches of swellings have appeared on my legs. after periods of standing my legs can be very painful. on my knees I have very tiny white spots which look as though they are under the skin. at the moment I am postmenopausal and am suffering with really bad hot flushes, I can have up to 20 a day sweating like mad. I do suffer from high blood pressure which I am on medication for. I have had many blood tests but they have all come back negative apart from me being postmenopausal. I am very tired all the time and find it difficult to function at times. can anyone help?
