question: Got a rush/hives all over my legs. It has been 6 days now and the itch is horrible. MY PCM stated that it is a classic hive from allergy. If I touch/scratch it, the spots, they "grow" in size and redness. Now, I am using Triamcinolone Acetonide cream .1% but it helps only for 1-2 hours. How long it would take to feel a positive effect from it? What else can I use since I am on 2 kinds of antihistamines?
