Is it normal for my lips and mouth to be itchy and tingly after eating tuna?!

The severity of allergies varies from person to person and can range from minor irritation to anaphylaxis — a potentially life-threatening emergency. While allergies can't be cured, a number of treatments can help relieve your allergy symptoms.
You may notice tingling or a prickling sensation in your lips, tongue and mouth a few minutes after eating tuna if you have a tuna allergy. Your lips, tongue, mouth and throat may become itchy after eating tuna if you have a tuna allergy, and the itching may begin immediately after you eat the tuna.
Anaphylaxis is a condition that you may develop if your allergy to tuna is severe, and signs of it include dizziness, low blood pressure, a weak pulse, vomiting and loss of consciousness.
It seems like you have a mild allergy to either Tuna or Seafood.

You have an allergy. Stay away from tuna and pineapple.

I happened to mention to my doctor once that my tongue gets itchy and a little swollen when I eat walnuts. He cautioned me to stop eating them because you never know how severe your reaction might be. He said that anytime my throat could swell shut and it could be life threatening.

I get that after watermelon, MSG, and chili.

You sound like it's a mild allergy. It can come up suddently ( ie you could have eaten these all your life, then siddenyl boom), and it can go away suddenly too.

My allergy came on sudden, and got so bad, I could not breathe. My whole face puffed up and throat got very very tight.
WHeezing and completely unable to breathe properly, it was weird.

Nope, that sounds like a mild allergy.

no love only after cock.
