There is a popping sound in my lower back.

Why does my knee make a clicking sound when I sit down and then stand up?

It's just like that, I hear a clicking sound from my lower back.

A cracking sound occurs when I bend my waist to the left side.

Is it necessary to go to the hospital for something like this if there's no pain?

I accidentally discovered a sound, and when I took the same position, I heard a clicking noise.

At first, I just thought it was okay for the first couple of times, but since I keep hearing the noise, it's becoming bothersome.

Should I go to the hospital once?

If you're going, it would be best to go to the orthopedic department, right?
