Hello,
Thank you for asking at HCM.
I went through your daughter's history and would like to make following suggestions to her:
1. A severe congestion/blockage of nose can also make her feel like "can't breath".
2. If she has
wheezing, chesty
cough or breathing difficulty like fast respiration, etc, there is possibility of
asthma.
3. The best thing in my opinion would be to get her examined by a doctor at the time of breathing difficulty. He will examine her chest with stethoscope to best determine whether she has wheezing or signs of asthma.
4. Cottonwood exposure can cause allergies as well as can cause respiratory symptoms directly also.
5. I would suggest her
allergy testing which will help her identifying the substances she is allergic to and also to know how to avoid their exposure.
Hope above suggestions will be helpful to you.
Should you have any other query, please feel free to ask at HCM.
Wish your daughter the best of the health.
Thank you & Regards.
