Following a recent check at the metabolic unit , I have to have an Echo - Cardiogram so they can prescribe different drugs rather than Byetta , both feet are now discoloured left being the worst as it's purple but my big toe is white & all toes now numb yet I have good pulses I have also had oedema for years now yet when I see my GP all they say is sorry we can't help you as I have a multitude of other problems linked to Klinefelter Syndrome ( very little is known re: the Adult side ) of this genetic anomaly so when I see nearly most medical GPs' , Consultants , Genetic specialists they are stumped & class me as basically knackered which is harsh to say the least , I have all these problems & no - one wants to know so They have told me to get on with life as there's nothing they can doe for me ! Getting rid of the pain would be a big help !
