Can you develop an allergy to green peppers?

Yes. My son is allergic to green beans. It causes swelling around his eyes, he scracthes his tongue and even gets a rash on his chest and back if he eats enough of them. However, he can eat peas (such as blackeye peas). He can also eat peanut butter.

I have a nephew who is allergic to all legumes (that means, no peas, no beans and absolutely no peanut butter). You should have yourself or your kid checked to be sure of the extent of the allergy.
