What does the S1 nerve root affect?
(Numbness for the S1 nerve runs on the outside of the foot. The S1 nerve root also supplies innervation for the ankle jerk (tap on the achilles tendon and the foot goes down), and a loss of this reflex indicates S1 impingement, although it does not create loss of function.
How serious is nerve root compression?
Nerve root compression that is severe enough to cause weakness in the arms or legs requires prompt diagnosis and surgical treatment because compression leads to death of the nerve cells and can permanently affect the function of the sensory and motor nerves downstream from the point of compression.
How do you fix S1 nerve compression?
Common injection treatments for L5-S1 include:
- Lumbar epidural steroid injections. Steroids injected directly into the spinal epidural space can help decrease inflammation and reduce the sensitivity of nerve fibers to pain, generating fewer pain signals.
- Radiofrequency ablation.
What is the S1 nerve responsible for?
Pain may radiate from the buttock, down the back of the thigh and calf, and into the foot, mainly on the inside of the foot. S1 Pinched Nerve: The S1 nerve root exits below the S1 vertebral body, which is responsible for calf muscles, which allow for plantar flexion, or pressing down like on the gas pedal in the car.
How do you fix nerve root compression?
Treating Nerve Root Pain
- Taking non-steroidal anti-inflammatory drugs (NSAIDs)
- Interventional techniques such as nerve blocks (spinal injections)
- Epidural injections in the lumbar and cervical spine.
- Nerve killing procedures such as radiofrequency ablation.
- Engaging in exercise and physical therapy.
- Activity modification.
