allergic rhinitis
"Singulair was wonderful for my allergies.  My allergies are only in my ears causing popping, crackling, clogging and pulling.  From the 1st dose I felt better and kept improving until my ears were better than they had been in months.  Unfortunately, on day 10 I developed tremors in my hands and lower arms.  The tremors turned into shaking when I tried to use my arms/hands.  My legs felt detached from my body.  So it was wonderful for my allergies but horrible for side effects.  Hopefully it won't take too long to get out of my system so the tremors stop."
