I was born with asthma but i have phases where its good then bad (worsens with allergies & exercse). is there a way to make to make it better?

Absolutely!: It sounds like you need to talk with your doctor about starting asthma and allergy controller therapy. There are several prescription medicines that, if you use them every day, will keep your symptoms under better control and allow you to get back to normal activities. There have been many olympic athletes who have had asthma but did great because they used their asthma controller medicines.

Yes: Regular exercise, avoid allergens, stress management strategies, avoid pollution, smokers and lung irritants. Take your medications regularly when needed.

Yes: Avoidance of triggers and regular controller medications can really help. I'd suggest a visit to an allergist.
