Uncomfortably Numb

Fifteen years ago I was perched awkwardly on a telephone exchange ladder for too long in one position, identifying faulty circuits in a cable replacement job. This resulted in permanent nerve damage to all toes bar the big one on each foot.

I've done something (unidentified)* today to trigger major numbness in the toes of my right foot. It's not sciatica, I know that sensation of old, this is quite different and feels plain weird.

*It’s Raynaud’s Syndrome, a condition whereby a nerve spasm in the feet constricts minor blood vessels, leading to whitening & numbness plus chills in the affected toes.
