I have come to the point with my back and hip pain where sweatpants is about all I can wear. I can't even wear most underwear. Any constraint at all around my hip flexors, hamstrings, lower back just yields excruciating pain after just a few minutes. Jeans are completely out. Most days I can't wait to get home so I can switch into my pajama bottoms.
Physiotherapist, doctor, chiropractor, all shrug and look confused when I describe this.
Luckily my employer doesn't care what I wear to work.
Dress sweatpants could be a lifesaver for me.
