Storm Keating was rushed to hospital and underwent emergency surgery on her spine, in what she has described as "the most frightening week of my life."

The Australian fashion designer, who is married to Ronan Keating, shared the details of her "long and trialing week" on Instagram.

Keating said she was rushed to hospital last Saturday with a "very bad prolapsed disc" which needed surgery. It then "escalated to Cauda Equina Compression Syndrome which required emergency spinal surgery to avoid permanent damage."

Keating said she feels "very lucky but wouldn't wish what I’ve been through on anyone."

She also thanked her family for "holding down the fort" while she was in the hospital this week.
