Does Increasing Dose Of Abilify Cause Resting Tremors In Left Side?

I take 15 mg daily of Abilify, along with Lamictal and Zoloft for Bipolar II. For the past six months or so, I've been getting resting tremors on my left side - mostly in my forefinger and thumb and in my knee. They go away when I move the affected areas. I am going to see a movement disorder specialist next month, but I'm wondering if the Abilify has something to do with the tremors. I have been taking Abilify for over six years now, but it's been just lately that the tremors have begun. I should also say that I went from 5 to 15 mg of Abilify back in October of 2012. Thanks,Bill
