I'm sorry you are still struggling with the numbness. It is good to hear it's not a real relapse, but it sucks that you can get no relief.
I'm numb from head to toe and it waxes and wanes for me constantly. I try not to acknowledge it to myself (denial), in hopes it will disappear back to a minimum level.
Good luck with the dentist. I hope you are feeling like yourself again soon.
