I actually had an unknown allergic reaction to something on an American Airlines flight way back in 90-91. 2 nurses on the flight said thats what it looked like. It itched like hell and I broke out in welts over my chest. I begged every person on that plane for a sudafed and was dumbfounded that the plane didnt have epinefrin on board.(Epi-pen from the olden days). Ice packs were all I could come up with till we landed then I rushed to Little Creek medical and they got me settled down.
Crazy memory from decades ago. I am itching now.
Sudafed won’t help with an allergic reaction.
That’s simply a decongestant.
You need Benadryl.
A friend whose son is SEVERELY, life threateningly allergic to the slightest trace of nuts, told me that she carried a bottle of the children’s liquid cause that’s what got into your system the fastest.
Aside from carrying multiple Epi-Pens.
