What is Sciatica?
Sciatica is a symptom of a problem with the sciatic nerve, the largest nerve in the body. It controls muscles in the back of your knee and lower leg and provides feeling to the back of your thigh, part of your lower leg, and the sole of your foot. When you have sciatica, you have pain, weakness, numbness, or tingling. It can start in the lower back and extend down your leg to your calf, foot, or even your toes. It's usually on only one side of your body [1].
Causes of Sciatica
The causes of sciatica are variable and include musculoskeletal, dermatologic, infectious, neoplastic, and vascular disorders. In many cases, the symptom is usually caused by degenerative disease in the spine with the compression or irritation of the spinal nerve [2].
Common conditions that can cause sciatica include a ruptured intervertebral disk, a narrowing of the spinal canal that puts pressure on the nerve, called spinal stenosis, and an injury such as a pelvic fracture [1].
Sciatica can also be caused by an injury, such as falling, or spinal or sciatic nerve tumours [3]. In some cases, the sciatic nerve can also be compressed by the piriformis muscle in the hip if it's either in spasm or extremely tight [4]. In rare cases, a cancerous mass can pressure your sciatic nerve [5].
Vitamin B12 for Sciatica
Vitamin B12, also known as cyanocobalamin, has been studied for its potential effects on sciatica. Research suggests that Vitamin B12 may promote recovery after peripheral nerve injury, which could benefit conditions like sciatica [6].
In a study involving rats with sciatic nerve injury, Vitamin B12 improved oedema and myelination, which are crucial for nerve health and function [6]. However, it's important to note that another substance, alpha lipoic acid (ALA), was found to be more functionally effective in the same study [6].
Another study found that Vitamin B12 and other B vitamins significantly reduced thermal hyperalgesia, a symptom often associated with nerve damage. All of which suggest that vitamin B12 could help alleviate some sciatica symptoms [7].
However, it's important to note that while these studies suggest potential benefits of Vitamin B12 for sciatica, more research is needed to fully understand its effects and determine the optimal dosage for this specific condition.

As always, it is essential to consult with a healthcare provider to determine the appropriate dosage suited for your needs.
Alternative methods of treatment for sciatica
Acupuncture: Acupuncture is one alternative method of treatment, where a practitioner inserts sterilized needles into specific points in your body. This method may help improve back pain symptoms associated with sciatica [3, 8]. In a study involving 230 patients, acupuncture in combination with herbs resulted in an average pain reduction of 62% [3].
Chiropractic treatment: This is another alternative method to relieve some pain. A chiropractor can adjust your spine to increase spinal movement, improve spine function, and decrease pain [8].
Massage therapy: By applying motion, pressure, tension, or vibration to your body, a massage therapist can help relieve pressure and sciatic pain symptoms [3].
Biofeedback therapy: This is a mind-body technique, that has been shown to improve back pain and chronic pain. This technique uses electrical sensors to help you understand how your body responds to stress and pain [3].
Mindfulness meditation: Meditation may also help reduce pain and improve quality of life. Committing to a regular practice can potentially help with sciatica pain [3].
Percutaneous electrical nerve stimulation (PENS):This method has also effectively managed sciatica. In a study, PENS was more effective than transcutaneous electrical nerve stimulation (TENS) in providing short-term pain relief [9].
It's important to note that the effectiveness of these alternative treatments can vary from person to person. Always consult with a healthcare professional before starting any new treatment regimen.
