Finger joint

Originally, trigger finger syndrome was present in the middle finger.

These days, besides that, my finger joints feel stiff when I wake up in the morning.

It's okay when I stay active, but since it happens every morning, it worries me.

Is it because I'm getting older or is there some other reason~~

If I get really sick, I'll go to the hospital, but since it's just a minor concern, I'm just watching and waiting.
