Each person has their own unique reaction to allergies, so no one can tell you what your reaction will be. Wheat swells the cells in my body - arms, joints, feet, brain, everywhere, so that when I am gently bumped, it feels like I've been hit with a hammer. I hurt all over, can't walk up stairs, my brain doesn't work, can't form sentences and it is difficult to comprehend what is said and process incoming information. It took me a year of avoiding wheat for the symptoms to subside so I felt that I was getting back to normal.
Now, if I eat a crurab of bread one day, I wake up the next morning with swollen joints, my knees hurt, and I can barely walk up stairs, and my brain doesn't function well. It can be in the most unexpected items - ketchup, ground beef, soy sauce made from wheat instead of soy. They even coat conveyor belts that carry potato chips and corn chips with flour to keep them from sticking, and then it isn't listed on the package. It's extremely hard to get waitresses not to lay bread on top of my meal. My allergy doctor put me on a rotational diet, which is how I discovered which symptoms were caused by the wheat. I always felt much worse the day after the wheat day. I have multiple, severe allergies, food and inhalant, so teasing out which symptom is caused by which substance is very difficult.
I highly recommend finding a good ENT allergy doctor to help with this.
