| Rash or Hives only in USA
I am an Australian who has been travelling to USA annually for the last 6 years.
Every time I visit the USA, after approx 4 or 5 days I break out in itchy, red bumps (hives?) all over my torso and upper arms. The outbreak lasts as long as I stay in the USA, and subsides almost completely within 24-48hrs after returning to Australia.
I have stayed at different hotels each time, so I don't think bedding can be blamed, and there is not a particular food I believe triggers this...
What could it be in USA that I am so allergic to, that does not exist in Australia. I travel the world extensively for work and have not experienced the rash in any other region either.
Antihistamines (Benadryl) does not seem to help at all.
Is there some food additives/preservatives that are unique to USA that I may be sensitive to?
Thanks in advance
