I listened to the podcast Ologies with Alie Ward, episode "Dolorogy (pain) encore with Rachel Zoffness"
She interviews a pain psychologist about chronic pain and ways to treat it. I learnt a lot about pain and how it works and highly recommend it!
Update about my shorts that I posted about. They needed to have a less slanted front crotch curve and fabric moved from side to CF. I worked It out thanks to the book "The fitting book" and I can't recommend it enough! The striped ones are my final toile that worked.
Made a new post with all the pictures. The crotch overall length feels good, maybe a bit of a wedgie at the back. I have shortened the front crotch length because I made a toile and it was too long. I know my CF droops down a bit but this is how I like my pants to fit for comfort. What do you think?
