BL-40 (back pain, knee pain, hot flashes)

BL-40, Wei Zhong (Middle of the Crook), is located in the center of the back of the knee. It’s the Ruler of the Lower Back, so I often use it to treat lumbar problems. It’s also great for deep knee pain and to cool the Blood* – try it if you’re overheated next summer, or if you’re suffering from hot flashes. Other good points for lower back pain: LV-3, GB-34, Du-4.

*Remember: The Chinese concept of “Blood” is different from your physical blood. I am not talking about your literal circulatory system. :)

The Knee

Let’s talk about the knee joint. It’s not quite as complicated as the shoulder, because it doesn’t move in as many directions. Having that kind of mobility with all of our body weight on top of it… well, that would be a recipe for disaster.  Instead, we have a modified hinge joint. The knee folds, but it also twists a little bit. The trick is keeping this twist under control.

Collateral ligaments run along each side, and the cruciate ligaments (named so because they form a cross) inside the joint create stability. Strong quadriceps (a set of 4 muscles on the front of thigh), hamstrings (three muscles in back of thigh), adductors (inside) and abductors (outside) also support the knee. Slick cartilage lines the surfaces where bones meet. The meniscus, a pair of special horseshoe-shaped cartilage structures, help absorb shock and guide the movement of the femur. And there’s a bursa on top of the patella (kneecap) to provide some extra cushioning. Pretty neat design, huh?

Sp-9 treats the knee, and drains Damp (a concept in Traditional Chinese Medicine).

If your gait is off, it can affect your knees and eventually your hips and back. Good shoes are important for knee health. Avoid heels as much as possible. If you have flat feet, use shoes with good arch support. To prevent injury, frequent light workouts are best. If you are a bigger person or have joint issues, try to reduce impact: walking or using an elliptical trainer is better than running, and staying on grass or a rubber track is better than concrete.

 

 
    Did you know that babies are born without kneecaps? They have a cartilage wedge but it doesn’t ossify (turn to bone) until about 3 yrs old. Lucky for them – It makes crawling around on a hard floor much more comfortable.
Acupuncture can reduce inflammation, increase blood flow, relax tight muscles, and speed healing. I can also do Osteopathic medical massage to break up scar tissue, release myofascial adhesions, and retrain the neurological system. This allows chronically tight muscles to return to normal. In most cases, therapeutic exercise is important for complete healing.
