As a disc degenerates, it can herniate (the inner core extrudes) back into the spinal canal, which is known as a disc herniation (or a herniated disc). The weak spot in a disc is directly under the nerve root, and a herniated disc in this area puts direct pressure on the nerve, which in turn can cause pain to radiate all the way down the patientâs leg to the foot .
Approximately 90% of disc herniations will occur at l4- l5 (lumbar segments 4 and 5) or l5- s1 (lumbar segment 5 and sacral segment1), which causes pain in the l5 nerve or s1 nerve, respectively.
* l5 nerve impingement from a herniated disc can cause weakness in extension of the big toe and potentially in the ankle (foot drop). Numbness and pain can be felt on top of the foot, and the pain may also radiate into the rear.
*s1 nerve impingement from a herniated disc may cause loss of the ankle reflex and/or weakness in ankle push off (e.G. Patients cannot do toe rises). Numbness and pain can radiate down to the sole or outside of the foot .
Foment bag help to resolve the back pain, leg pain and discomfort caused by the herniated disc and heal the disc.
