Can i tell me how i can know if i have asthma?

Physician evaluation: Typically, asthma is a condition which is caused by your airways become more narrowed due to inflammation and constriction. Symptoms can be triggered by weather, activity, irritants, smoking, etc. Going to your doctor would be most helpful. You can prepare for this visit by remembering how frequently you have your symptoms, the duration, and what they are associated with. Good luck!
