<s>[INST] Hi, my boyfriend has a bubbly looking red rash all over his face, ears, neck, forearms, and partially on his back; I was guessing it might be shingles or hives but I'm not a doctor. He's tried Benadryl since yesterday and it's getting worse; any ideas? [/INST] Hello, The symptoms seem to be related to shingles. I suggest using Acyclovir cream for local application. I also suggest Cetirizine relieve the symptoms. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Dorina Gurabardhi, General & Family Physician </s>
