Most people think of asthma and think wheezing, shortness of breath, tight chest and coughing. There are often other signs of pending attacks as well. I've found that the earlier I recognize a pending attack, the faster I can get a jump on treating it and trying to keep the severity of the attack down. Watching for these signs has become part of my asthma action plan.

Asthma Early Warning Signs:
itchy chin
itchy or sore throat
dark under eye circles
stuffy, runny or congested nose
tiredness
mood change--grouchy or extra quiet
itchy, glassy or watery eyes
thirst
sneezing
stomach ache
headache
fever
restlessness
eczema flare-up
sweating
heartburn
change in face color- pale or flushed
throat clearing
restlessness
heart beating faster
trouble sleeping
yawning

I think this covers most of the symptoms. If any body has to add any thing, most welcome.
