Hi and thanks for the query.
If there are blisters that have started to weep and are spreading then she needs urgent medical attention at an ER or the Urgent Care.
Administration of antihistamines like benadryl or loratidine 10mg twice a day will help with the itching.
However, the hospital will examine the sores and dress them after scrubbing and decontaminating them. To prevent secondary infection on the sores, she will require oral antibiotics which will be prescribed by the doctor in the ER or the Urgent Care.
Hope this helps.
