How Can Shortness Of Breath Along With Chest Pain Be Treated?

So i have alergies. I thought it was to sulphites it began with raspberries, then wine and champagne i finally figured it out so stopped eating any kind of cakes as raspberry is usually there, i dont drink any wine or champagne and inhave also had a severe couldnt breathe alergy when some1 sprayed perfume on me soni havent worn perfume in over a decade.... however the other night i went for chinese with friends and had a major reaction (for me it means really hard breathing, i can breath but my chest is tight and its really hard to fill my lungs its like really short breaths, but my face and chest come up with large patches of bright red and its burbs so hot. I have an epipen but have been too afraid to use it bacause indont knownwhat it will make me like also i have never stopped breathing it just gets very hard in the past inhave really hyperventilated then for a couple of days after my chest hurts... what i will add is that im a big beer drinker so its not alcohol in ots entirety that im alergic too.. i havent been alergy tested as i know they will spend weeks and weeks of my life checking for nuts and wheat and all the usual stuff and i know it isnt. What could it be.
