If you’re not diabetic and you’re prone to ingrown toenails, this could be self-inflicted
Dr Yau said: “Ingrown toenails otherwise tend to occur where the nail has been damaged or cut too short, producing sharp edges.
“Equally, ill-fitting footwear which squeezes the toes together can encourage the nail to grow inward.”
Make sure you wear shoes that fit properly and make sure you cut straight across your nail rather than the edges and don’t cut them too short.
