To the OP, just to make sure for your sake, were they organic? I know bananas have a thick skin, but you might as well try to see if it was a pesticide thing or an actual fruit thing.
Twice while living in South Carolina I bought peaches from a roadside stand, and twice my mouth and lips went completely and totally numb, and I felt ill. Very very freaky. I had a strong feeling it was a pesticide issue, and I've never had a non-organic peach since. Never had that reaction again, either.
It's interesting that you should mention being allergic to bananas. I had no idea that they were allergenic, but I recently stopped eating them (amongst a million other things) trying to figure out what was really hurting my breastfed baby! He stopped shreking in pain, but I'm not sure which food did it, or if it's his reflux medicine that's helping him. I've been too afraid to reintroduce anything, but I was eating a lot of bananas, and now I'm thinking they may be the key.
Aw, good for you! You're getting lots of support through LLL, family and friends, message boards and the like, I hope? If not and you want someone to bounce ideas off of, feel free to PM me. Let's put it this way, I quit LLL b/c I knew more from growing up than I could ever have learned from those women...I am my own nursing support group.
When DS was new I was taking grapefruit seed extract for a yeast issue, then for some unknown reason ate a HUGE grapefruit, and for the next 2 days DS had the nastiest (non-yeast) diaper rash...poor kid. I cut out the grapefruit after that, just wasn't worth having it go through me in such quantities!
Good luck all in figuring out your reaction! My aunt is allergic to avocados, and no one ever believes her!
