Ear pain during flight

I usually get severe ear pain during flight descent and this time I have a bad cold as well. I have my flight tomorrow and I am extremely scared that the pain is going to feel much worse. I do use my ANC activated earbuds (Oppo Enco Air 2 Pro for reference) but even then I do feel like my ear aches a lot.

Kindly give suggestions for sure shot ways to minimise this pain.
