actually food allergies don't have symptoms they are reactions it depends on how well your body can tolerate it and then there is something called anafalactic where your body just can't take it, and you stop breathing, your lungs swell up, you get hives, and you need the epi pen other than that it could just be an irritation everyone actually has an allergy to pineapple it just depends on how well you can tolerate it that you can call it an allergy but i hope your okay

and different allergies have different reactions, so you can't really depend on the internet to determine if you have allergies or not the only way to say that is to take an allergy test, where they use a needle to put a tiny bit of pineapple on your skin, mainly your back, and then they monitor you for about 15 minutes to see what happens. After they see a reaction from the surface of your skin, mainly swelling or hives, they give you a tiny bit for you to swallow, and then they monitor you for about 35 minutes for any swelling in the neck, hives in the stomach, or sniffling stuff like that. It also could be anything else in the pineapple juice that you could be allergic to. Have you talked about it with your parents yet?

ok you should try to look into allergy testing when your comfortable im just saying its probably most likely an irritation, but im not too big of an expert .-. the only allergies I have are eggs and all nuts- sooooooo like and the only reactions i have is vomit and anafalactic. so yeah
