Nail Bed Infection

It begins inconspicuously. A small pulling at the nail edge. A spot that throbs faintly when you grip something. Then it swells. The skin becomes red, taut, warm. A drop of pus collects under the nail fold. Every touch, every pressure, every accidental knock becomes a small pain experience. The fingertip — otherwise the quietest, most agile tool of your daily life — makes itself known with an intensity wholly out of proportion to the size of the inflammation.

Medically, the process is clear. A tiny injury at the nail wall — a crack in the cuticle, an irritated spot after manicuring, a micro-injury you didn't even notice — has become an entry point for bacteria. The immune system responds, the body sends defence cells, pus forms. In stubborn cases, it is lanced, flushed, treated with antibiotics. So much for the surface.
