Could Slight Numbness And Tingling On My Tongue From Oikos Greek Yogurt With Blueberry Pieces Indicate An Allergic Reaction?

So I was eating Oikos Greek Blueberry Yogurt with whole blueberry pieces in it and every bite I took I had a slight numbness and tingling on my tongue and a sensation where it felt like it was trying to swell that would quickly go away after each bite but built on itself if I didn t eat it slowly. I am not allergic to yogurt as I do not have this reaction from other brands or as strongly of a reaction and can eat Frozen Yogurt just fine. I also do not have a blueberry allergy either. However when I eat fruit based Oikos Greek Yogurt, I have that temporary tongue numbing/tingling feeling each bite. Could I be allergic to some kind of additive or flavoring they put in the mix? Does a slight tingling or numb sensation warrant ceasing eating it or will I still be ok if I just pace out the consumption?
