I m 53 and within the last year or so I think I ve developed an allergy to peanuts/nuts/peanut butter. When eaten late at night I ve end up having scratchy throat, and coughing which sometimes has led to vomitting. Last night I mistakenly ate some store bought candy that had peanut butter and nuts in its ingredients. I had similar symptoms into the early morning hours which ended with a black liquid coming from one nostril. It was like a faucet had been turned on with a steady stream of a black liquid. It lasted for a number of seconds, then quit. Any thoughts? I don t remember this happening before and if it had, nothing to this extreme.
