Its seems that would make more sense having the tickle because of a post nasal drip the diffentially could be but its really bad I feel it as I write tickle tickle tickle my eyes water from it.
I still have my thyroid, but do have sinus issues- I was told it was part of the thyroid package....when I laugh I gag and sometimes have vomited.....even going up steps brings the cough on.....sometimes it is worse then others.....if urs is a cold , then I do not know what mine is,I 've had it for years!
good luck
Godspeed
