Supplementation for vitamin B12 deficiency should be provided parenterally since poor oral absorption is usually the cause of the disease. Supplementation with vitamin B12 typically halts progression of the disease, but does not reverse it since much of the disability is secondary to the spinal cord pathology.

Is tingling a sign of nerve healing?

It is important to differentiate this tingling from the pain sometimes produced by pressure on an injured nerve. The pain is a sign of irritation of the nerve; tingling is a sign of regeneration; or more precisely, tingling indicates the presence of young axons, in the process of growing.

How long do damaged nerves take to heal?

Regeneration time depends on how seriously your nerve was injured and the type of injury that you sustained. If your nerve is bruised or traumatized but is not cut, it should recover over 6-12 weeks. A nerve that is cut will grow at 1mm per day, after about a 4 week period of ‘rest’ following your injury.

How much vitamin B12 should I take for nerve damage?

Although treatment regimens of B12 injections vary, some doctors recommend injections of 1,000 micrograms (mcg) of vitamin B12 daily for five days followed by the same amount given once a week for five weeks, and then a lifelong dose of one injection per month, containing 100 to 1,000 mcg of vitamin B12.
