Can Xeomin cause difficulty swallowing?

Last year, I had two rounds of Xeomin injections in my 11s, crows feet, and forehead. I had a second treatment about two months later with significantly more. (I don't recall exactly how much but in total it may have been about 30 units?) This gave great results that lasted a couple of months. However, after the second treatment I developed difficulty swallowing about two days later. I was frequently choking mildly on food. This lasted for about 4-6 months. Could this be related?
