My relative has been itching after any/all foods for more than 30 years. She scratches her jaws & neck until they are almost like leather. She remarked that the only thing that stopped the itching was when she has had steroid injections in her knee or back- the itching stopped for about 6 weeks. She is in her 80s, has pretty good health and is within the healthy weight range. She takes medicine for HBP, an antidepressant & 1/2 pill to help her sleep. She has been using gold bond medicated ointment to help with the itching and sometimes ice, with little/no relief. No hives, bumps, etc. and the only redness is from the severe scratching.
