The 28-year-old has Ankylosing Spondylitis, a rare form of arthritis that causes pain and stiffness in the spine.
Lomax said his art related to his experience, explaining how he treated surfaces with body rub before applying bubble bath to get forms and shapes that replicated how his spine felt.
He then merged images of his spinal x-rays on to the paper.
He used QR codes and binary to write a message that would read 'contaminated' when scanned.
Lomax's exhibition at Cathedral Junction has finished, but his work can be seen here.
The work is Lomax's final project for his Master of Creative Practice at Ara Institute of Canterbury.
