Botox in Masseters Resulting in Buccal Fat Pad Herniation - New York, NY

Pros: Last time I had this treatment done, I loved the result. I loved my more contoured, feminine jawline, and the atrophy of my masseters has really brought out my cheekbones.
Cons: This time, I had the same amount injected, but it seemed to have caused an over-weakening of my left masseter, resulting in "pseudo-herniation on the buccal fat pad." When I smile, a distinct lump is visible next to the left corner of my mouth. It messes up my facial balance and causes asymmetry. The left side of my face looks like it did when I was 15 years old: chipmunk cheek.
I had 40 units injected in each side. Why this only happened to one side, I don't know. I'm praying this goes away once the botox wears off...in the mean time I'm chewing lots of gum to rebuild the muscle. If this doesn't resolve by itself, I'll need to either have the fat pad pulled out (buccal lipectomy) or have it resutured into its previous position (this is a much better choice for me, as I'm only 18 and having a one-sided buccal lipectomy at this age would surely result in extreme facial asymmetry later in life). If any of you have had a similar experience from treating your masseters, or if you know a very skilled doctor who may be able to shed some more light on this very specialised subject, PLEASE share your thoughts. I'd love feedback as this condition is causing me extreme anxiety and depression.

I think it may be getting slightly better. No one has ever heard of this side effect before. I believe I'm the only one to have ever experienced this.

I doubt anyone is reading this, but, just in case, I'm positive it's better than it was in these pictures. By quite a lot. I'm absolutely not able to demonstrate the asymmetry to this degree anymore. I feel comfortable smiling despite a slight imbalance and "tight" feeling in the affected cheek. I will update in two months.
