hmmm, I've heard of people being allergic to mango, but usually if it's a rash reaction to food it would show up sooner than that! anything else new? Different dryer sheets, soap, shampoo, etc.? I guess you could wait a couple weeks and give mango again.
Also, I thought that you couldn't have an allergic reaction teh first time. You would have to have had the mango 2x to get a reaction, right??
