My doctor said it was allergy based which makes sense because it is accompanied by varying ear pain, nasal drainage and an itchy throat. I have been put on
Allegra-
D which drastically reduced the symptoms. I am a military aviator
and I'm restricted from taking certain medicines. The last six months, I have been in a non flight duty and started taking benadryl which I am normally restricted from taking due to the drowsiness side effects.
