This is the story of Sarah Hannah, 23, from Glasgow, Scotland.
I was diagnosed with psoriatic arthritis at 16.I had a lot of joint pain, a lot of swelling and stiffness. That was making me really tired, I couldn’t do anything, it was making me really miserable. I was on holiday in Vegas with my family, and I was in the shower, and my wrist was so swollen and painful I couldn’t turn the tap off. We decided when I got home I needed to go and see a doctor because it was getting quite out of control.
