Hi,
I have had these symptoms for about 3 years. A cough, clearing my throat, lightheadedness dizzy, no spinning or vertigo though, ringing in ears. I started taking the OTC Chlor-trimeton and most of the real bad symptoms went away (I was almost incapacitated). I have been taking the drug for about 2 years. Still clear my throat and cough have slight ringing and lightheadness.
I have been to 4 allergists, they agree that I must be allergic to something, but they are out of answers. I have been to countless other specialists, ENT, Brain, Etc. all negative.
I have also been allergic to seasonal stuff for 25 years (tree pollen, grass) etc. But, this is all the time.
The antihistimines that I tried at first, were the ones that didn't make you sleepy. Like allegra or clariton. They did not work for me. I tried the OTC Chlorotrimeton, which does make you sleepy (it has a 'brain component' in it). I was feeling much better in about 2 weeks.
Anybody out there who has or knows anything about this allergy?
