What Causes Itchy Hives On The Body After Travelling?

My mom and I just returned from a trip in Vietnam on 7/24. Before we landed she developed some throat constriction, but not severe. Then she developed itchingness and after that, she developed hives all over her body. Her doctor gave her Benadryl shot, start her on a short course of prednisone, Vistaril po prn. Nothing seems to help. She has had 2 more shot of Benadryl, has tried po Benadryl, phenergan, Zyrtec, hydrocortisone cream, triamcinolone cream. This is now more than a week. Allergy test was done and pending result, anything we should be worried of? Will ask for script for Epipen just in case. She s now just got started on Medrol dose pak

Hi,

Allergic reactions, chemicals in certain foods, insect stings, sunlight exposure, or medications can all cause histamine release. It's often impossible to find out exactly why hives have formed. ... Acute urticaria: Hives lasting less than six weeks. The most common causes are certain foods, medications, or infections.

Hope I have answered your query. Let me know if I can assist you further.
