Think of your sciatic nerve like a high-voltage line running from your lower back down through your hip and leg.
When it's healthy:
- Signals flow clean
- Movement feels smooth
- Nothing hurts unless something is actually wrong
But after years of rotational golf stress, that line doesn't snap.
It doesn't tear.
It starts to lose power.
I call what happens next the
Nerve Signal Depletion Effect™.
Because what's happening isn't just irritation.
It's drain.
Over time:
→ Microcirculation around the nerve sheath weakens → Nutrient delivery to the nerve fibers slows → Cellular energy production inside the nerve drops → Signal transmission becomes unstable
In plain English: your nerve runs out of fuel.
And this is the part nobody warns you about.
When a nerve runs out of fuel, your pain stops behaving like an injury.
It starts behaving like something you can't predict.
One round you feel fine. The next round, by the 11th hole, your leg is on fire and you have no idea why. One morning you get out of bed clean. The next morning you can't put your sock on. There's no logic. There's no pattern. There's no "I tweaked it" moment to point at.
That's not because you're imagining it.
That's because a depleted nerve isn't following the rules anymore.
And when a nerve runs out of fuel, it doesn't go quiet.
It does the opposite.
It becomes hypersensitive.
Movements a healthy nerve would ignore — the follow-through on a 7-iron, walking from the cart to the tee box, getting up out of a recliner — start firing pain signals that don't match what you just did.
Your nerve isn't damaged.
It's underpowered.
