Too much Botox in masseter? What's the best nonsurgical step to correct asymmetry? (Photo)

Hi What is the best non surgical next step to help correct my facial asymmetry? I got 15 units botox on my right jaw two months ago, and another 10 units a month ago. The muscle itself is stronger than the left side, but isn’t especially strong anymore ( have been treating with Botox for over five years). I still have on and off very bad jaw pain on the right side, but I think it now looks like it might be over treated from the Botox, and I just got filler on the left side to help square that
