question: my 84 year Mother broke out in what at first we thought was shingles on her back but her doctor said no that it looked like an allergic reaction.   he sent her for allergy testing and said she was allergic to milk.  he put her on singular, Pepcid, and Benadryl.  the sores on her back and arms are dry patches now but driving her crazy.   she is itching continuously.  she  can't sleep or relax.  the doctor gave her some lotion that doesn't help.  any suggestions to help relieve the itching would be greatly appreciated.
