Allergies and facial twitching

My son( who just turned 8) has had a stuffy nose and itchy water eyes for a while now, worse as the summer months role in. He has allergies and was given nasonex and some allergy eye drops (which we have not give yet as our pharmacy had to order more)
Anyways for about a week now he has been having weird facial movements. His eyes and eye brows move and sometime he scrunches his nose while twitching his eyes. His doctor did not seem concerned with it at all and said it was probably due to allergies.
I am wondering if anyone else child had weird facial movements due to allergies and if so did they go away?
** Also at the doctors office he did not even have one facial twitch and the DR was trying to make him nervous which I guess should increase the ticks, also he was wondering what he looked like when he twitched so he sat in the mirror and without fail he didn't have a twitch.. I have no idea what is going on!!!
Please help
Thanks

Recently I have seen posts similar to this about facial twitching on the child behavior and the pediatrics forums...I keep coming back to allergies, possibly environmental, from toxins in our air and outside .Do some research about the spraying being done and if any toxins maybe a cause .
