asked

Within the last several years, whenever I consume crab, my tongue numbs shortly after and stays numb for one to two days. I am 60 and love crab, but now I consume much less. No other fish or shellfish has the same reaction. Is this an allergy I have developed or a toxin unique to crabs only? Can brushing my teeth and tongue shortly after consuming the crab lessen the symptom? Is there a drug I could take to counter the effects, like Claritin? Or, is this a precursor to something else?
