The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
Yes: Nerve injuries do recover if the ends of the severed nerve are sewn together by a hand surgeon. Beware that it is a very slow process. Nerves grow back 1 inch per month from the cut end out to the finger tips, so expect months before feeling may start to come back, though initial feeling may be more like the pins and needles of a nerve waking up before any quality sensation comes back. ...Read moreSee 1 more doctor answer

Unlikely: Batson's plexus is the name for the veins that surround the vertebral bodies. Veins are very compressible so they are unlikely to cause any pressure on nerves. ...Read more
Not typically: The batson's plexus significance is that it's a network of veins without valves. Typically veins have valves, due to the low pressure in the venous system, to decrease the chance of flow backup within the system. The batson's plexus connects the deep pelvic veins & thoracic veins, & with no valves can easily serve as conduit for infection/cancer cells to travel from pelvic structures to the spine. ...Read more
Yes: In some cases, marked benefits occur with infusions of ivig, and we know that diabetics who take metanx experience fibre re-growth and multiplication after about 9-12 months. If problem due to treatable condition such as celiac disease or sarcoid, might also see reversal. Uncover the precise mechanism of the disorder, and treat appropriately. ...Read more
No recourse: A crushed optic nerve (how did this happen to you?) causes permanent changes which will alter the vision sometimes severely. There is currently no treatment known for this and a transplant is not possible. A discussion with a neuro-ophthalmologist would be helpful in this situation. ...Read more
If bulging disc pressing against thecal sac/transversing nerve extrudes downward, does nucleus flow down pressing against nerve or can it seep, around nerve? If seep, can traction pull damage nerve?
Disc herniation: When a disc herniates and causes pressure against a nerve, pain, numbness, tingling, and weakness can result. Not only can the disc material cause mechanical compression, but it can also incite an inflammatory reaction that can irritate the neural elements. Traction or tension on a nerve that may be tethered against a herniated disc can also cause sciatic-type pain from a bow-stringing effect. ...Read moreSee 2 more doctor answers
Possibly: Nerve injury implies some kind of damage to the nerve itself. While spinal cord and nerves are both nervous tissue, nerves typically are structures that have branched outside the spinal cord. Injury to the sciatic nerve, for example, is not considered a spinal cord injury. They are very different structures. ...Read moreSee 1 more doctor answer
In WHIPLASH INJURY the nerves originating from spine inside vertebral column, CAN NERVES SNAP OUT? Due to rapid movement of neck.
No: Short of a traumatic displaced fracture or dislocation of the spine, the nerves do not "snap out" of their normal position. They are protected by strong ligaments and the bone architecture of the vertebral column that would have to be disrupted for them to move into an abnormal position. ...Read moreSee 1 more doctor answer
Yes: Acutely compressed nerves can result in muscle twitching, muscle spasm and typical painful radiation patterns. This is due to the abnormal signal the nerves are now sending to the muscles which are reacting to its signal. Sometimes this is an involuntary action in which the nerve is reacting like a reflex arc that is on replay. This cycle of nerve signaling needs to be broken to improve this. ...Read more
