Question: how do you tell the difference between psoriasis and eczema?
Answer: Subtle Differences in Itchiness Millstein says, "Psoriasis tends to cause milder itching and, in some less common types of psoriasis, a terrible burn. Eczema, on the other hand, can lead to very intense itching. When it starts to become severe, some people scratch their skin so hard that it bleeds."
