Difficulty Wearing Pants

Hello,
I would like to open a new post to share my "problem".
Over the past few years, and I feel like it's getting worse, I've had more and more difficulty wearing my pants.
No visible allergic reactions, but I have a feeling of discomfort throughout the day.
So I tried to look at detergents (I use Arbre vert BIO), the method of drying pants (online/washing machine), but no explanations.
I have several jeans at home, some are acceptable, only one is very acceptable, and for the rest, it's a nightmare when I wear them.
I of course looked at the compositions...The one I can support is made of the same materials as another one I can't stand.
I'm starting to think about a psychological blockage, because I realize that even before putting on one of these pants, I'm already thinking about it...
What do you think?
Thank you in advance for...
No one to address my problem?
Despite my research, people have the same problem, but few solutions...
Pumice stone to "soften" jeans + superfatted soap.
I'm going to try both but without much conviction
