I have heard that some people really like those Pajama Jeans...the As Seen on TV ones. Haven't used them myself but it's what I've heard.

I actually have different jeans that I will wear based on my pain levels...looser ones which are flannel lined for bad days, regular weight boot cut denim for "normal" days, and the lighter weight stretch denim ones for days in between. I don't wear anything that is too tight. For really bad days I have some sweatpants that I got at Gap which have no elastic in the waist (I have RSD there too). Since my RSD is in my ankle I make myself wear socks every day. The socks themselves hurt but they protect my ankle from worse pain too from cool air and the clothing. The hardest thing has been finding shoes that I like that I can tolerate on my foot...that don't hit me in the wrong spot. But after almost 3 years I finally have 3 pairs that I like that also fit my style.
