I'm almost 2 months on T and all of a sudden my jaw joint on one side feels really sore and stif. I didn't do anything to hurt it.  Could it be from the T ...like a growing pain....anyone else experience this?

yup! i also experienced weird growing sensations in my face/neck/shoulders. my face has slimmed down a lot, my neck got wider, and my shoulders broadened. t is working its magic

I didn't experience pain in the joints like you, but definitely in the jaw muscles. It'd be completely random-seeming at times. It could be from something easy to chew and suddenly the apple would feel more like beef jerky from how tired my jaw muscles would get. My jaw has definitely squared out and broadened in appearance.

Good to know thanks for the replies
