As one ages, can certain foods cause ones skin to itch, especially at night!? It keeps me awake most every night, ...especially on my lower legs ( and lately on my waist and hip area....itch,itch! I have many ltions from dermotologists, which work for an hour or two, but then, back again, the itching! I end up washing the lotion off and sometimes I get back to sleep, but it's never certain I will. Terribly annoying! My age? Hard to say it...help!! (85) !
