Psoriasis is an auto-immune disease. It can be helped by a good chiropractor. I had it bad from 6 months old until 13 years old. A chiropractor got rid of mine in 16 weeks by adjusting my spine 3 times a week for 16 weeks. Just be sure and get a good chiropractor. The palmer school of chiropractic graduates are one of the best. I did not have it come back until in college when under a lot of stress. I go to a good chiropractor every 2 weeks. Hope you have good luck with keeping it under check like I have. Chuck
