If you have low back pain, you may feel it where the
pelvis (illium) and the base of the
spine (sacrum) meet – the sacroiliac
(SI) joints.
However, it doesn’t always mean that the joint is the cause
of pain. It is most likely the
joint is irritated because of the tilt/twist of your pelvic structure. A lot of muscles are attached to the
pelvis, so if one (or more) of them gets tight pulling the structure one way or
another, you feel pain in the SI joint.
Quite often, low back pain is
actually originated in your buttocks.
Common trigger points for the low back pain in the buttocks
are below the top ridge of the pelvis (iliac crest) toward the hip in the
gluteal muscles (gluteus maximus, gluteus
medius).
They don’t normally hurt themselves until you press on them,
and they are surprisingly tender. It’s effective to use a tennis ball to
massage the sensitive spots than a pointy self-massage tool.
If low back pain comes on after standing or walking, or you have sciatica, massage in the middle of the buttock (piriformis), especially at the edge of the sacrum and the top of
the thighbone. It could be very
tender.
Please read the guidelines for massage in the previous post.
I strongly recommend you receive a massage in the buttock area from a massage therapist. If you are new to the idea, please read my posts FAQ: Does a massage therapist work on my buttocks? (with a video) and FAQ: Should I take off my underwear?.
