This is a first.. help!

[Java]

Noticed yesterday, after my girl's secondary misting, that her mouth is now slightly warped. Ever since I went away for a week in February, leaving her to the mercy of my roommates (it was an emergency and the only thing I could do..), I noticed she's had shaky muscles and twitching. She was never much of a climber and preferred her food literally handed to her.. but lately she's been having more shakes and now this.

I have and have had many frogs in my life. She's the first Cuban.
Have had her for a year, since she was a baby.
She's in a 20 gallon tank to herself that stays around 81 degrees. It has held pothos for a long time. A few weeks ago I introduced a safe seasonal and safe ivy.
Crickets are bought specially dusted and fed as needed (roughly 3 times a week. She'll eat about 2-3 depending on size.)
I give a nice misting to the tank twice a day. She has her pool to soak in when she wants.
I hold her about once a week or when she demands to be held.
She's not much of a climber but still is able to when needed.
She is not impacted. Honey bath makes her poop within a minute or two.

I wonder if it's MBD? I can't find anything on Cuban Tree Frog health wise and vets around me refuse to see her; I'm kind of tackling this blind. My other frogs are fine, even.
