Do you live in a cold weather climate? This time of year an asthma attack can be triggered by the cold air. Wear a scarf when going outside to cover your mouth and nose.
If the cold weather isn’t applicable than you could have exercise induced asthma. But it’s rapid onset makes me think more of an allergen that you’re breathing. Does it always happen at this time of year? Again I don’t know where you live so I can’t suggest possible allergens.
You best bet is to have your doctor refer you to an allergist or pulmonologist who can manage your asthma.
God bless you and keep you healthy.

1Call your doctor. When you notice that you are experiencing symptoms, such as difficulty in breathing, especially during the fall or spring, increased coughing, sometimes with phlegm or mucous production, and feelings of tiredness or exhaustion, call your doctor and make an appointment. Your doctor will perform several tests, such as the lung function test, to determine the percentage at which your lungs are functioning. He may also order allergy testing to find out if your symptoms are related to allergies

I can send you this hypnosis thing that is supposed to help you manage your asthma. I have been using it and it has really improved my breathing. It’s kind of like telling your brain and your body to heal your respiratory system. It’s not as freaky as everyone makes hypnosis up to be, it’s just like relaxing and getting in tune with your body.
