(Concern) Hip joint pain

I have been walking nearly 10,000 steps every day for four years. Recently, my hip joint sometimes hurts. It also makes cracking sounds, and I feel pain, so I'm worried. These days, I have been reducing walking and mainly swimming, but I still experience pain.ㅠ

I was less worried because it's a part that constantly hurts, but hip pain is a serious issue.

I'm upset because my joints seem to be aging faster than my age, and I worry that I've been overusing them all this time.

My father also had both artificial hip surgeries. Can it be caused by genetics? Please recommend good supplements or stretching exercises for the hips.
