What to do about prolonged allergy reaction
We are currently traveling, since around 6 days ago my wife suddenly had a allergic reaction to something causing her to break out in red spots (without bumps) on her arm joints, knee caps, foot and hands which itches and swells. She has been taking claritan D and benedryl but that helps only a little. Yesterday she went to the ER and they gave her an IV with an antihistamine and anti inflammatory corticosteroid with 2 days worth of the same in pill form. She just finished all the pills
Today she was better but as soon she she went out and the temperature changed, the red bumps and itchy feeling came back. On another day she was fine for the whole day until she took a shower. We are extremely frustrated with this since we are still traveling and this does not seem to be resolving itself. We have pretty much eliminated anything new she has came into contact with in terms of food, clothing, products etc. What should we do at this point if antihistamine drugs only helps temporarily and it has been a week?
