I have narrow eustachian tube and have not infected fluid in my ears. How do I get rid if I can't take allergy meds due to anxiousness effects?

Gum. Often chewing gum may create a pumping type movement of the eustachian tubes and help to remove some fluid. There are also those who recommend xylitol...Either as a nose spray or chewing xylitol gum.
Different meds. Plain antihistamines, like Claritin (loratadine) or zyrtec, should help. If not better, be seen by your physician or ent, and you may need a tube in your eardrum to let it drain.
