Olfactory Nerve Damage
Which brain structure receives information from all of the senses except that of the olfactory nerve?
Somatosensory: Post central gyrus of the Parietal lobe. ...Read more
A complete nerve transection will leave an area totally numb. The distribution of the numbers depends upon where the nerve was cut. A partial nerve injury may leave the area tingly or incompletely numb. Finally even if the nerve is not cut the swelling and bruising to the tea can affect the nerve as well. Usually we consider sharp penetrating injuries as likely having nerve lacerations when sensation is lost. A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend ...Read more
I lost my taste from having the flu about a year ago will it ever come back ? Can the olfactory nerve heal?
Waiting a Year?: You have waited a year without any specialist evaluation and treatment? Please go see an expert in this field. Your family physician will help you with that. ...Read more
Lost taste/smell 5 mos. ago after URI, should I see a Neurologist or wait it out? Heard it can take up to 2 yrs. for the olfactory nerve to repair.
I mix lot bleach and toilet cleaner and was exposed to a powerful gas for few seconds. I jumped into fresh air. Did i damage my lungs/olfactory nerve?
Unlikely: If bleach or toilet cleaner touched your eyes, you would need to go to ER asap. Otherwise, if you just smelled fumes, you likely have not caused any permanent damage in your lungs or nerves. ...Read more
Yes: If the damage does not cause the nerve to be completely cut, then healing can occur. If a nerve has been cut, it will need to be reconnected in order to grow. Nerve grows about 1 mm/day, so depending on where the injury is, it may take over a year for recovery. It is difficult after a nerve is cut to get 100% recovery, but some return of sensation can be expected after repair. ...Read more
Sometimes: A broad question, because there are many ways a nerve can be damaged: compression (carpal tunnel), crush, cut, etc. A "bruised" nerve can heal itself; it grows back at about 1 inch/month. If the nerve is divided, it may occasionally heal, but more often needs surgical repair--and this doesn't always result in return of function. ...Read more
Variable: Generically, if only the coverings of a nerve are involved (myelin), and healing begins, it will take about 4 weeks. If the central portion of the nerve fibre is involved (axon), recovery is the speed of finger nail growth (.1 mm daily). Depends on location, causation, and whether successful treatment is available. ...Read more

Etiology: First find out why it is happening. There could be many reasons such as secondary to a disease like diabetes, a lack of a specific protein, a herniated disc in your back, a nutitional deficiency, an injury. First you need to find out why you got it and then you can move on from there. ...Read more
Pudendal Nerve: Root value is s2, (racepinephrine) s3, s4. If you have a L1 fracture, (pretty far: 5-6 inches from s2: l1, l2, l3, l4, l5, s1, s2, (racepinephrine) s3, s4, s5) in order to affect spinal cord and s2, (racepinephrine) 3, 4, a lot more things including strength in lower legs would be affected. If your strength in your legs fine, it would be difficult to imagine you affected the fibers coming out lower. http://www.pudendal.com. ...Read more
EMG-NCS: can overlook nerve damage in several ways. First, the condition may not be involving the particular nerves studied. (wrong nerves tested). secondly, as is often the case with autonomic and pure sensory nerve involvement the condition can escape detection because it is in a mild stage or we have no baseline with which to compare it (this is why nerve biopsy is sometimes ordered) ...Read more
It depends: It depends on the area of the brain or spinal cord involved and the severity of the involvement. There are numerous possible answers to your question. ...Read more
Theoretically and in reality it does not happen because nerves are very slippery and movable , and the acupuncture needles flexible.Because of that it is virtually impossible to pears a nerve.
Of cause care is being taken that nerves are avoided .
Acupuncture points are located along the fascias(very thin transparent tissues enveloping the muscles) and usually away from the nerves. ...Read more
Cubital tunnel: Most commonly, ulnar nerve is trapped at the level of the olecranon fossa at back of the elbow, and treatment can involve medication, pt, steroid injection, or surgical nerve transfer out of harms way. Less common, is involvement of median nerve at the front of the elbow. An EMG study can help guide treatment interventions. ...Read more
Yes: Some nerves give feedback to your brain and spinal cord, helping your body to protect them. When they fail, the joints can be exposed to excess force without you knowing it. This is called a neuropathic (or charcot) joint. It is seen fairly often in the feet of people with the neuropathy (nerve damage) associated with diabetes mellitus. ...Read more
DependsOnTypeInjury: If the nerve is crushed, given time it will probably grow back on its own in 1-2 yrs.If it was severed, it may or may not repair itself.Physical rehabilitation can help the re-wiring process.Also, if the nerve is injured due to inflammation, neuroprolotherapy may help function return. ...Read more
Possibly: Men that have had back surgery especially lowered in the spinal column in the area where the nerves control the reproductive area may develop subfertility. This surgery may compromise the ability to ejaculate and maintain erection and may even possibly affect sperm production. ...Read more
Here are some...: First, one needs to figure out what & why makes you think that you have penile nerve damage. So, collect the related information on the onset, degree, & progress over time with its sequence of events, & bring those to Doc for anylysis, physicals, & possible tests so to deduce possible Dx for proposing possible Rx. But, up to now, there is no known Rx to solve nerve damage, but lifestyle may help.. ...Read more
Variable: If the nerve is cut and repaired at the original surgery, the prognosis is usually good, but recovery can take about one year. This is because the nerve regenerates only about one inch per month. Alternatively, if the extent of damage is uncertain after the original surgery, physical therapy is prescribed for three months. ...Read more
Neuropraxia is defined as a temporary loss of function of the nerve. Some nerves are purely sensory while others carry both sensory and motor fibers. Traumatic contusion injuries to nerves or nerve compressions can cause Neuropraxia. Sensory nerves like sural nerve in the leg or mixed sensory and motor nerves like the median and ulnar nerves in the forearm & hand ...Read more
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
