Hi.  I ate some pistacio pudding this weekend.  My mouth including the roof of my mouth felt like they were on fire.  Even my gums became inflamed.  The next day had rash on chest.  I have had blod tests for allergiws in the past but nothing showed.  Should I retest for nut allergies?
Welcome. Yes it's a localized flare n the fact that u just hot a rash on the chest means it was systemic too. Take Ben Chat Doctor.  Thanx
