What causes numbness on the tongue after drinking coffee?

When I drink anything with coffee in it my tongue starts to go numb and feeling like it is swelling. I enjoy ice caps so i tried to make one at home to make sure it wasnt something added to it like a fake sugar.I don't know is someone can be allergic to coffee. It affects my tongue and it makes me feel a bit sick.

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

As per your explanation it looks like an allergic reaction, and if it occurs everytime you take coffee then it can be probably due to allergic reaction to coffee only.
So my suggestion is that for a confirmation you should consult an Emergency room or an Allergist and get evaluated and a clinical evaluation and a blood test can be done to rule out the exact cause of the symptoms.
Of it is allergy to coffee then taking coffee and other foods containing coffee should be avoided.
For now also you should avoid taking coffee and if the tongue is swollen you should take anti allergic medicine like Levocetrizine as too much swelling of tongue can cause choking.

Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Honey Arora

Have strange tongue sensation--tongue feels unsettled, sometimes it feels like its moving. Feels like I m not pronouncing or enunciating words especially those starting with s mcorrectly. No one else hears this..maybe in my own mind--anxiety. No problem swallowing or slurred speech, nothing no one has brought to my attention. can this be an allergy--perhaps from green tea. This has been going on for the past few weeks and I ve been drinking fresh loose leaf green tea since late April.

I bet my tongue after falling. I have a broken tooth and the other side is pretty sharp. (I m 46). Thursday it will be 2 weeks and roughly the end of it 1/2-1 (?) is numb. The sides aren t painful but I do have a bit of a lisp. It feels like I ate something hot and I burnt it.

Yesterday I woke from a brief nap and ate a snack. After I ate I started feeling my tongue and lips getting tingly and numb. shortly after I felt a migraine coming on. I have gotten those before and usually use Frankincense oil on my temples and behind my ears and they go away. So that is what I used. my ear was hurting so I got a Qtip and cleaned it and the auras of the migraine went away, I was telling my friend and she said maybe I had a mini stroke. I have not ever had heart problems. but I am 60. are those symptoms of a stroke?
