Did incorrect Botox injection cause inflammatory lymph nodes in my cheeks?

Hello, I had Botox injections into my masserter last year. Id had this done many times to help with my teeth grinding. This one particular time was with a new practitioner, ever since I've had puffy/swollen pockets above the injection site. It's really bothering me as it's given my face a squishy appearance when I smile. I went back to the practitioner who seemed clueless to what it could be. I've had lymph drainage which helped a tiny bit. How would I treat this? Any advice is appreciated :)
