Asthma: Sounds serious if your medications and nebulizer are not helping, head to the emergency room right away. Don't wait until the morning.

See allergist: You need to see an allergist to sort this out. One of the potential causes is vocal cord dysfunction which is more commonly found in young women of your age. This disorder often co-exist with asthma.
