Concern about finger joint arthritis

I think I have had finger arthritis for about 7 years.

But I have never received treatment at a hospital..

Lately, I've been really worried about my finger arthritis. I guess you could say it's affecting my quality of life...

Recently, I was looking for treatment methods on YouTube and found a good stretching technique that was very helpful. I want to share it with others.

This is the condition of my fingers.. Especially my little finger, it hurt just by touching it, but the pain has improved a lot.

I'm also curious if treatment at the hospital is effective.
