Herniated Lumbar Disc, info from AAFP

Good info’ but PLEASE don’t use this as your sole source or in place of a competant diagnosis.

Specific movements and positions that reproduce the symptoms should be investigated during the examination to help determine the source of the pain. For example, the upper lumbar region (L1, L2 and L3) controls the iliopsoas muscles, which can be evaluated by testing resistance to hip flexion.

While seated, the patient should attempt to raise each thigh while the physician’s hands are placed on the leg to create resistance. Pain and weakness are indicative of upper lumbar nerve root involvement. The L2, L3 and L4 nerve roots control the quadriceps muscle, which can be evaluated by manually trying to flex the actively extended knee. The L4 nerve root also controls the tibialis anterior muscle, which can be tested by heel walking.

The L5 nerve root controls the extensor hallucis longus, which can be tested with the patient seated and moving both great toes in a dorsiflexed position against resistance. The L5 nerve root also innervates the hip abductors, which are evaluated by use of the Trendelenburg test. This test requires the patient to stand on one leg; the physician stands behind the patient and puts his or her hands on the patient’s hips.

A positive test is characterized by any drop in the pelvis on the opposite side and suggests either L5 nerve root or hip-joint pathology. Possible cauda equina syndrome can be identified by unexpected laxity of the anal sphincter, perianal or perineal sensory loss, or major motor loss in the lower extremities.

T12-L1 Pain in inguinal region and medial thigh, Motor deficit: None

L1-2 Pain in anterior and medial aspect of upper thigh,Motor deficit: Slight weakness in quadriceps; slightly diminished suprapatellar reflex

L2-3 Pain in anterolateral thigh, Motor deficit: Weakened quadriceps; diminished patellar or suprapatellar reflex

L3-4 Pain in posterolateral thigh and anterior tibial area,Motor deficit: Weakened quadriceps; diminished patellar reflex

L4-5 Pain in dorsum of foot,Motor deficit: Extensor weakness of big toe and foot

L5-S1 Pain in lateral aspect of foot,Motor deficit: Diminished or absent Achilles reflex

Hope this is of interest!

Sure is.

Thank you for posting this. I’ve had what looks like L2-L3 symptoms over the last few weeks, but seems to be resolving thanks to NSAIDS and stretching/foam rolling. Prolonged walking/standing can re-exacerbate sx. Thankfully time off work and Dr. availability finally came together for my apt. this Friday.
