I, too, have maddeningly itchy
joints in my feet
and sometimes in my knuckles. I have scratched them until they blistered, scratched the blisters until they broke and hurt, then medicated them and bandaged them because the pain was tolerable, whereas the itching was not. I also have fibromyalgia and, having read the responses of others here, I think we both should start keeping a food diary, annoying as that is.
