I have fought ecxema all my life, since birth, but not much anymore since I have learned how to keep it gone. They still don't know what causes it and some creams don't help when the dermatologist recommends them. My palms itch but I see nothing. My face itches at times but I have always had dry skin.
I don't know if it has anything to do with diabetes because I had it at birth. Diet is associated with rashes in some cases. Look there. The last cream I had prescribed came from a new doctor who looked into the matter because it was my doctor's day off. The cream helped some. I try to go to the doctor on my doctor's day off now. I can't get an appointment anyway, so I avoid them. Read on the web. Sometimes the nutrition advice helps. Sometimes I use only plain olive oil on my skin. It made Cleopatra have better skin, I read. Avoid stress.
Actually, quit stress. I remember closing down my kitchen, leaving a note and going to my other little farm house overnight. I would get a phone call asking if I was coming home to cook dinner, and I replied "I don't know." That usually changed the attitude for a while and I had better cooperation. I finally learned to put my foot down in middle age and got some relief from the stress. Now I have none at all as a widow but it is still a lot of work. Dorisena
