(Concern) Knee pain

I have been making walking a daily habit for nearly two years since I installed the 10,000 steps walking app.

It was said that strength training should be done after a comprehensive health check.

I work on my lower body at the gym three days a week.

Recently, I finish with stair exercises, but my knees when climbing stairs

It's so painful to climb because of the pain.

Lately, I've been experiencing persistent knee pain, and I'm worried about it.
