Peanut Allergy

Last friday, before we went to the cabin me and my husband ate peanuts at home. I really liked the peanut. Until by that afternoon while we where heading to the cabin I started feeling ichy. And im thinking of anything I ate that is salty because in the Philippines everytime I ate salty foods it caused the itching. But that day I couldn't remember of any salty foods I ate and I was thinking about maybe peanut causes this itchyness but that cant be because I have been eating any kinds of peanuts in the Philippines. But thats the only food I can think causes my itchyness. Untill today I still feel itchy but I will not scratch myself really hard it might leave ugly looking spots. Hope that this will go away soon.
