psoriasis
"I am a registered nurse and have had psoriasis since I was 12. I am now 56. It was mostly contained to my scalp during the winter months. But I started experiencing psoriatic arthritis which was getting worse in my hands and feet. 
1 month after starting Stelara, I noticed a difference. It has been 9 months and I have no more psoriasis or arthritis pain. 
I did not experience any side effects. I highly recommend this product."
