Get your lung function test checked...
presents with sudden onset breathing difficulty and wheezing
. Symptoms are more pronounced during cold
temperature; hence most patients experience symptoms late in the evening and during cold / raining weather. However many other symptoms can mimic asthma and only means to differentiate is through a lung function test.
This test is performed at a chest physician office. It is an out patient procedure. Doctor will record your lungs ability to breathe during breathless times and after giving you a specific drug.
You can contact a chest physician (pulmonologist) to learn about the test. I do not think we have any other means to determine if you have asthma.
Hope it is clear. You are free to ask for clarifications.
