Sweetz, If you and your doctor have established your what I call your "red, green and yellow light" peak flows, that's usually a pretty good indicator for me. But then on the other hand, when I am at my very worst, I don't wheeze. I don't have enough air left to wheeze, I can barely whisper. Are you treated by an allergist? Are you a fairly new asthma patient? If it is all new to you, it takes a while to learn to know when you are really in trouble.
What usually happens when you have an asthma attack?
