If you do not know if you have asthma, these 4 symptoms could be signs that you do:
Coughing that sometimes wakes you up at night.
Wheezing, or a whistling sound when you breathe. You may hear it more when you breathe out. It can start as a low-sounding whistle and get higher.
Breathing problems that include having shortness of breath, feeling like you are out of breath, gasping for air, having trouble breathing out, or breathing faster than normal. When breathing gets very difficult, the skin of your chest and neck may suck inward.
Other Warning Signs
Other early warning signs of an asthma attack are:
An itchy neck
Dark bags under your eyes
Being short-tempered or irritable
Feeling nervous or edgy
Call 911 or your local emergency number right away if you have any of the following symptoms. These are signs of a serious medical emergency.
You are having trouble walking or talking because it is so hard to breathe.
You are hunching over.
