Yes, that's an allergic reaction.





Be very careful; you don't want to go into anaphylactic shock, which is when you have a severe and life-threatening allergic reaction.





If you experience the same thing from any other peanuts, I recommend seeing an allergist.





---Edit---





So do you buy the peanuts unshelled, or do you buy them shelled and take the shells off?





Sound's like you may be allergic to the oil on the shells. Just don't lick the shells, and you'll be fine.Why do my lips get very big whenever I eat pistachios?
It sounds like you are sensitive, or allergic, to pistachios. Pistachio allergy is common. Pistachios are in the same plant family (Anacardiaceae) as mangoes, cashews, and poison ivy. You may also be sensitive to mangoes and cashews, be careful when you eat them.





If you are allergic, it may either get worse or better with time. Usually, the more you expose yourself to an allergen, the more serious the reaction becomes. It's possible that if you abstain from pistachios for several years, you might lose your sensitivity.





You should also be sensitive to unshelled pistachios. Maybe you're just eating fewer nuts when they are unshelled and the reaction is less.
Yes, this is an allergic reaction.
