Over the past week i have noticed i am wheezing a lot more than i have done in the past (everyday, i have to use my inhaler until it wears off then use it again otherwise i will keep wheezing), i find that i usually wheeze when im sitting down.. If i am active i do not notice nor wheeze as much. I have also started waking up in the morning with severe wheezing (relieved by a Ventolin inhaler) and coughing. What could be causing the problem? Also does using the inhaler too much cause migraine like headache symptoms? Thankyou.
