They are the last 2 vertebrae in your spine.  Mostly you would think of the pain associated with the lower back if one or both of these vertebrae are subluxated. Subluxations (misalignments) in this area of the lower back can mean much more serious issues than back pain. Although lower back pain and sciatica are helped by adjustments every single day thankfully! But, let’s dig a little deeper into anatomy & physiology to find out what else may be affected by Subluxations here. The L4 & L5 nerves are associated with the muscles of your lower back, knees, legs, ankles, feet and toes. Also, the prostate gland and the sciatic nerve are affected. Some symptoms that could be associated with L4/5 problems could be sciatica, low back pain, poor circulation in the legs, weak or painful feet/ankles, weakness in legs, frequent urination or bladder control issues. It’s a good thing to have a well-adjusted L4/5!
