A routine kidney stone turned into a life-or-death crisis for Louise Marshallsay, culminating in the amputation of her fingers and toes and an 11-month journey to reclaim independence with cutting-edge prosthetics.
From Stabbing Pain to Septic Shock
In July 2022, the former teaching assistant from South Wales felt familiar stabbing pains and learned a small kidney stone was present. Sent home to pass it naturally, she collapsed hours later as her hands and feet darkened to black and purple.
Rushed back to hospital, Marshallsay woke four days later to septic shock-organ-threatening blood-pressure crash-necessitating restricted circulation that starved her extremities of blood.

Amputation and Recovery
- Fingers and toes died, requiring removal in October 2022
- Thumbs spared, aiding future prosthetic grip
- Right-ear hearing also lost
> “I was horrified when I looked down… I saw each finger being taken away from me.”
She moved in with her parents to relearn daily tasks while mourning her changed body.
Prosthetics Breakthrough
| Step | Process | Outcome |
|---|---|---|
| 1 | Wax finger carving | Patient-chosen nail shape |
| 2 | Silicone molding | Skin-tone color match |
| 3 | Vein & crease detailing | Hyper-realistic finish |
> “They looked just like the real thing… I was overwhelmed.”
Adapting to a New Normal
- Wears prosthetics daily
- Shares story publicly
- Focuses on being present for her daughter
Key Takeaways
- A small kidney stone can trigger fatal sepsis
- Sepsis survival may require drastic measures like amputation
- Modern silicone prosthetics offer life-like restoration
- Gratitude outweighs grief for Marshallsay
She now calls her survival a miracle, determined to move forward with resilience and hope.
