At home pain relief?

I was prescribed carbamazepine by urgent care for suspected trigeminal neuralgia which I just started today, 200mg 2X daily. I was also prescribed sumatriptan as a rescue med, which I have not taken yet.

Since it seems like the carbamazepine will take at least a few days to show relief, what are some things I can do OTC/at home to help? I’ve been religiously clinging to my heating pad. Tried lidocaine cream and orajel. Would love to know what helps you besides prescriptions.
