red when she scratched. She got skin tested and they said, tomatoes - she didn't like tomatoes, but avoided tomatoe products (catsup, sauce, pizza), no help. They said, latex/rubber - spent a fortune (she was BUSTY) on non-elastic underwear, avoided all rubbers of any kind, no help. Happened to read a magazine article that made a reference to scurvy
, with symptoms. Went out and bought grapefruit (she hated anything sour or tart) and after three days rash GONE. After that she took a daily Vitamin C supplement and no more rash. (I'm sorry, have to the use the past tense - it's 41 years later and she has passed on.)
