Cramps aren't caused by muscle contractions; they're caused by irritated skin fold crossings.

The next time a cramp occurs, don't miss your chance to try this technique.
● Use your nail to probe your skin until you find the exact spot where the cramp originates.
You'll notice some kind of skin defect at that place, most often in the form of a depression.
You want to open it up.
The best way to do so is to repeatedly flatten it with your nail.
● Place your nail directly on the cramp's location, and apply all the pressure you can without hurting yourself.

● Repeat, repeat, and repeat again.

You can take action immediately or afterwards.
● ON THE SPOT: Applying pressure on the skin with your nail will eliminate the cramp.
However, many people won't have the courage to do this.
● AFTERWARDS: If a cramp bothers you because it occurs frequently, take the time to apply pressure on its location while you're not in pain.
With time, you'll feel your nail opening up the fold crossing; thus removing the tension inside the skin.
The cramps will become less and less frequent, and then disappear.

Your body is crisscrossed by cutaneous folds.
Some are horizontal, some are vertical, while others swerve or go diagonally.
But, one fold doesn't go far before it intersects with another fold.
That creates a fold crossing.

The fold crossing crater forms a deep chimney that dives deep into whatever is beneath the skin: muscles, tendons, bones, articulations, ... and the skin becomes attached to those locations.
Fold crossings become painful because your activities pull on them over and over.
People think that their muscles are to blame because they've been activating them just before the cramp.
In fact, it's the skin itself that bursts into a cramp.
If you press your nail on the place where you feel the cramp, you'll find a fold crossing.

Humans are fearful when it comes to pain, and they are too afraid to touch a painful spot.

Muscles can't feel much and are incapable of producing the intense pain you experience when you suffer from a cramp.
The pain comes from the skin.
Cramp locations are simply fold crossing locations.
You can't study these phenomenons with microscopes.
You have flat nails to do so.

Cramps aren't the only pain you can get rid of by grooming your skin.
Pain in the feet, the knees, the hips, the back, the shoulders, the arms, the hands, ... can all be relieved with your nails.

Special precautions and care must be taken when grooming your skin.
Grooming the affected areas may provoke unusual reactions, and even increase the pain.
Test-groom the regions for a few days before committing yourself to deeper work or exploration.
Be smart and go gradually.
Groom for short periods, several times a day.
