Frozen Shoulder

For months, my favored arm has had a smaller range of motion.
At first, I thought this sort of thing just came with getting older,
But now a diagnosis has revised my early notion:
Adhesive capsulitis, also known as frozen shoulder.

I don’t know how it happened; I am hardly diabetic
Or otherwise afflicted, and I never had a stroke.
I haven’t been immobilized; I’ve gotten more athletic.
I haven’t needed surgery, and nothing in me broke.

Whatever got it started, let me “capsulize” the issue:
To move, I need a fluid that will lubricate the joint.
Right now, my shoulder capsule (that’s a strong connective tissue)
Has thickened with adhesions, and it’s harder to anoint.

The good news is, my pain’s decreased; perhaps I’ve finished freezing
And now am in the second stage, with thawing on the way.
I’m going to some therapists, who stand to help with easing
Recovery; already I’ve made progress, so they say.
