Welcome Mike!

There are a few success stories on DietDoctor: https://www.dietdoctor.com/?s=psoriatic+arthritis

Also a great three part link to CrownMD on Chronic Pain:
https://www.dietdoctor.com/is-a-ket...l-pain-reliever This is "sciencey" but a great explanation how a very low carb diet can improve joint pain before there is much weight loss. I noticed my knees better after three weeks...but it never made sense until this explanation.

Also right here there are two sections; on General health
