Have had long-term Essential Tremors: Worried it might be more?

I have been diagnosed with benign essential tremor since I was in my teens and am now 53. I did have DBS surgery when I was 46 and it was a game changer for me but my shaking is getting worse. Does anyone else worry about maybe it’s something more like PD? I will wake up know with my hand/forearm shaking a little.
