My wife has eaten a few hazelnuts and then, five minutes later complained of feeling light-headed. She then began to burp consistantly. As the burping started - the light-headedness went off. She felt a sharp pain in the chest which she says seemed to disperse into her breasts before going off completely, but no pain down her left arm down her left arm. She kept her colour and maintained normal temperature. Now, 10 to 15 minuters later she feels much better but is burping consistently, once every 5 or 6 seconds! Does this sound like a nut allergy (which she has never had before) or does it sound like something else? if so, what? With Many Thanks. Steve.
