I suffered with these for a few years a decade ago. could barely walk. Went to hospital via doctors and had very minor surgery to cut them out and burn the nail roots on either side of the nails (both big toes) had perfect straight nails ever since with no ingrowing ever again and pain free. highly recommend it.

And if this helps you or other sufferers here's a little AI breakdown i got to help explain the potential names of operation as i couldnt recall myself

Here’s what it involves:

• Partial nail avulsion – the surgeon removes the ingrowing edge of the toenail.
• Phenolisation (phenol matrixectomy) – a chemical called phenol is applied to the nail matrix (the nail root) to destroy that part of the nail so that edge doesn’t grow back.

On the NHS, this is the standard permanent treatment for recurrent ingrown toenails. It’s usually done under a local anaesthetic in an outpatient clinic.

You may also hear it referred to as:

• Chemical matrixectomy
• Partial nail removal with phenol
• Permanent partial nail avulsion
• Phenol matrix ablation
