Question) Why does calcification occur in the shoulder and what are the symptoms?

I've been receiving injections, physical therapy, and manual therapy for shoulder pain for several months, but it still hasn't improved.

They say I might stay at the hospital for a while, but I am uncomfortable and in pain, so I hope to recover quickly through various treatments.

But I was diagnosed with adhesive capsulitis, and they also said there is calcification in my shoulder.

So, I heard that pain caused by calcification is somewhat different. Has anyone experienced shoulder pain due to calcification?

I'm curious about what pain caused by calcification feels like.

And I wonder why calcification occurs and whether it naturally disappears on its own.

And I would like to know what methods are used to treat calcification.
