Hello, My Father And My Brother Suffer From Asthma And

Hello,

My father and my brother suffer from Asthma and since last year I, every now and then, find it so hard for myself to breathe. 30 seconds of jogging on the street or walking by especially spicy restaurants make me suffer for at least 1-2 hours. But I don't have any coughing or wheezing and the only problem is that I feel the air I'm breathing only goes halfway into my lungs and sometimes I have a pain on my chest too.
I referred to a GP and she gave me a referral to go to a specialist for further tests. She also gave me an inhaler to use when I had such a problem. I used the inhaler few times but it didn't help me at all. Honestly, since I always hated this disease, I'm so scared to be diagnosed with asthma and that's why I don't go to a specialist for the tests. (I know it's childish but please don't judge me)

I would be so thankful if you let me know what possibilities can cause this problem.

Thanks
