 [ Symptoms ] sometimes my vision in my left eye goes away doctors have tried everything [ Disease ] i am sorry you are going through this but i doubt it has anything to do with your blood transfusions just to be clear eczema is not something that can be transmitted through an exchange of blood eczema is not contagious so you can rule out that theory i suggest you seek a medical opinion about the cause of the scaly itchy skin on your leg it could indeed be eczema but it might be something else altogether a medical professional can not only diagnose the problem but also prescribe an appropriate treatment wishing you well
