Can a blood test for allergies be wrong or is there other possible explications for my worsening sensativity to nuts? I used to be able to eat nuts regularly and LOVE them but in the last 3 years I have steadily had an issue with them. I had a blood test from allergist a year ago that said I was negative for all nut allergies. BUT I have not found a nut yet that doesn t make my tongue get a burning tingling sensation and then craters left behind. I have looked into geographic tongue since my tongue bothers me during my period as well. So linked to hormones? I used to be able to get an accidental nut in a cookie and be ok but not anymore. I took a drink from my sons gatorade and had a reaction in my lips afterwards -he had been eating ballpark peanuts. I cannot use lotions or soaps with almond in them but can still have almond extract in baking. Walnuts and peanuts are the worst. They both have brought on the strongest and quickest reaction. Walnuts have even started to affect my throat and cause minor swelling. Should I get retested?
