I have two cases of Bell’s Palsy that I was able to successfully treat. I did all the points that you did and then after DN, I massaged the area and performed a lot of assisted eye closing and facial muscle exercises (first passive then active-assisted, then resisted). Perhaps you are doing all that too and just specifically asking what points to activate but I wanted to share what I did. It looks David is suggesting some more advanced points which I did not do but I’m sure they would be helpful. Good luck!
