Acupressure for Low Back Pain: One Key Acupoint
Bladder 40 is used to relieve low back pain
Bladder 40 is the Command Point of the back.
Command Points are one of many categories of acupoints used in Chinese medicine. As the Command of the Back, Bladder 40 is an essential point to add into your sessions aimed at relieving low back pain. Regardless of the type of hands-on healing you practice, adding in acupoints is a way to offer more relief to your clients.
Bladder 40 acupuncture point
Acupuncture points are the same as acupressure points, acupoints, or simply “points.”
These acupoints were mapped out thousands of years ago in China. Throughout the ages, practitioners have used hands-on contact with these points in order to relieve pain. Hands-on contact is referred to as “acupressure,” while the insertion of very thin needles is referred to as “acupuncture.”
Bladder 40 is located behind the knees.

Bladder 40 is in the center of the crease at the back of the knees.
BL 40 is located right in the center of the back of the knee.
First, notice the crease that marks the back of the knee. Bladder 40 is at the center point of that crease.
The back of the knee is a vulnerable area.
Use very light pressure on Bladder 40 so that you do not injure the knee joint. By using gentle, circular motion you can activate Bladder 40 in order to help reduce low back pain.

Just stumbled on this after getting a massage and noticing how tender the back of knees were. Interesting, because I have been having a lot of lower back pain. Quick question – if one knee point is more tender, does that correspond with the same side of the back, or does it correspond with the opposite side? Thanks!
Hi Julie,
Great question – in my experience sometimes there is direct correspondence and sometimes not. Each of the 12 meridians is located on both sides and are in relationship to each other.
Some people say there is a “criss-cross” relationship, some say not. I notice what is real for each person and go with that. In practice, if there were pain in the left lower back I would massage the Bladder 40 points on both legs and ask my client what their experience is, and then use their experience to guide my work.
I hope that helps!

This is the big question!
My answer always begins with “it depends.” It depends on the person you are working with and their unique set of circumstances, along with you, and your unique circumstances.
