Why are nut allergy symptoms not posted everywhere?

I don't know. Allergic reactions to foods are all caused by the release of the same chemicals, mainly histamine, so have the same symptoms which consist of combination of the following: itchy/swollen lips/mouth/throat, nausea/vomiting, abdominal cramps, diarrhea, red/itchy skin, hives, runny/stuffy nose, chest tightness/wheezing, shortness of breath. Reactions occur within 1/2-2 hr after one bie/sip of food.
