My fingers swell and tingle during exercise (walking)ㅜ

I walk 10,000 steps every morning~

It was fine during the summer, but these days the morning weather is

As the weather cools down, I experience swelling in my hands.

I was walking diligently when I felt a tingling sensation in my finger.

When I look at my hand, my fingers are swollen and puffy.

I can't even make a fist.

My hands were swollen throughout the workout, and after I got home and washed them

If you rest, the swelling will go down as if it never happened.

It's been about a week now, and the symptoms are due to exercise.

Suddenly, is it because of appearance or because of a health issue?

I'm worriedㅜ

Should I rest from exercise and observe the symptoms, or go to the hospital immediately?

I'm wondering if I should go.

Perhaps about the phenomenon of hand swelling during exercise like mine

Please let me know if you have any advice.
