Shortness Of Breath More Condition_symptoms What Could It Mean If I Experience Severe Shortness Of Breath During Exercise?

What could it mean if i experience severe shortness of breath during exercise? - shortness of breath more condition_symptoms

I drive at least 3 per week doing cardio and lifting light. This week I was at expericing breathlessly in the middle of my training. Sometimes it hurts so much, I stop and breathe, because I feel dizzy and feel like I could vomit.

I am 26 years old, with a family history of hypertension and heart problems. I would be tested, but I am an independent student without insurance.

What could be the problem?
