I have been itching from my head to my thighs. No change in detergents, makeup, medications. Went to an emergency room three weeks ago while traveling. (The first couple of days two Benedryl helped but after then had no affect). I had been itching at that time for a week and while in the car riding for about three hours and could no longer tolerate it. They did blood test which showed right number of red and white and shape of blood cells but said I had inflammation in my blood vessels and viens but that was not cause of itching. They could not determine cause and treated the symptoms with a dose of steroids by vein and then prednisone for five days. Finished prednisone on 11/29 and yesterday started itching again. Blood tests from rhematalogist from earlier in Nov, Aug and May all showed elevated liver enzemies . I also have recently developed diabetes. Age 73, female, 5 3 and weight 230. Any ideas?
