Thanks for query on HCM.
Your symptoms and high eosinophil count
suggest some allergic episodes.
You have to start anti allergic medicines like levocetrizine,fexofenedin.Nsaid
with decongestant will be helpful to subside blockage of nostrils.
Steam inhalation at bed time will be helpful.
You will get recovery within 5 to 7 days.
If it is recurrent than i would suggest to go for allergy
test to find out any specific allergen so you can start prevention.
Start exercise,yoga and deep breathing exercise
after getting cure.
Consult your physician for further guidance and proper medical management.
