Rub the area between your eyebrows to loosen your neck and open your sinus

I have introduced this method to some patients who have had sinus problems. 
 
The self-care method is rubbing the frontal suture, which is a ditch on the frontal bone (Fig. 1). The length is about a inch.
Rubbing this area loosens your neck and opens your nose, and also loosens your chest and abdomen.
So if you have stiffness in your neck or sinus problems, or if you feel your abdomen is tight, try rubbing this ditch.
 
1. Rub the ditch-like-frontal suture with your fingers of one had like rubbing not the skin but the bone.
2. Open the frontal suture with your fingers of both hands. To get more strong contact, it is better to push your head toward your fingers.

If your fingers are slippery on the skin, it is more effective to place a piece of cloth underneath and rub and open the suture.
