A Couple Of Years Ago I Got Bell's Palsy And

A couple of years ago i got bell's palsy and pretty much most of the right side of my face was numb, yesterday around midday i felt my upper cheek feel tight, no numbness or pain, except i started to feel like my face was droopy, so today i woke up and i felt way better but there's still a slight discomfort and by face still FEELS droopy but it does NOT LOOK droopy and the tightness feeling is gone for the most part it's just a droopyness feeling and a discomfort, sometimes it goes away and i dont feel it, im anxious because is it possible the bell's palsy is coming back, or could it be something else since it's just discomfort and droopyness, should i get test done again? Or should i do what the doctors told me last time which was do face exercises and chew gum, when i did that it healed by itself, or should i be concerned?
