Does the discomfort last a long time after getting nasolabial fold fillers?

I am wondering how long the facial discomfort lasts after getting nasolabial fold fillers.

It might vary from person to person, but roughly how long does it take to recover naturally?

I wish I could go back to the days when I didn't have nasolabial folds.

From choosing a hospital to worrying about side effects, the stress is off the charts.
