Damaged Nerve Endings
Sciatic Neuropathy: Hello. Diabetes isn't usually associated with true sciatic neuropathy. It can result from nerve compression (tumor, hematoma, etc.) and injury in the gluteal region or thigh. In the gluteal region, it is most often caused by trauma (posterior hip dis;ocation, pelvic fracture). Nerve can be directly injured during an intramuscular injection into the buttocks. ...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 like to have my feet gently tickled most evenings, I find it relaxing. Can this damage my nerve endings?
No!: Compared to the stomping around we all do everyday, what can a tickle do? Enjoy your tickles! ...Read more
No: I am going to assume that nobody's using a device that will cause obvious physical damage or feels compelled to self-mutilation. There's no reason to believe this is anything more than just another tale made up by someone who wants to frighten young people about their developing bodies. If you're a young man with questions, dad might be a good guy to talk with. ...Read more
Frostbite: Actually frost-bite associated pain does depend on nerve damage. In fact every sensation you experience in life depends on nerve function. The function may excessive or underactive but the nerve is still functioning for you to feel anything. Transmitting unpleasant or undesirable sensation does not imply that the nerve is damaged but suggests something is going wrong somewhere. ...Read more
I had lis a month ago, for a fissure. Since surgery my anus still feels numb. Are nerve endings damaged by this? Is this permanent? Will it go away?
Yes: In a disease state called complex regional pain syndrome type ii. ...Read more
Yes: As a nerve regenerates, it can fire in erratic patterns, causing pain and tingling. This usually resolves as healing progresses. Pain can also be generated by the brain and spinal cord after the connection to a nerve has been lost- an extreme example of this is phantom limb pain, where an amputee feels burning pain in the limb after it has been removed. ...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
Yes and no: A severed or ruptured nerve theoretically can be repaired surgically, but that does not guarantee complete healing and normal function. Nerves do have the ability to regenerate. New connection can be made to bridge the area of injury. This takes time and most healing will occur within the first year after injury. Ultimately, your body will do the best it can to heal the injury. ...Read more
If too much: Any medication or drug can cause damage if taken too much and too often. Pain medications are designed to affect nerves to reduce the bad signals. They must be used appropriately or they can cause too much effect and result in damage. Abuse of pain medications has become a major problem. Many patients end up with chronic pain due to excessive use of pain medications. ...Read more

A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend surgical repair if needed. ...Read more
Not so simple: Need to provide diagnosis of cause so that the actual pathology can be addressed. If you possess a true sensory small fibre neuropathy, this does need confirmation via a skin punch biopsy. You could have an immune disorder, amyloidosis, diabetes, b-12 deficiencies. Repair maybe possible, and medical foods may be useful. A few neurologists deal with these problems and can guide you. ...Read more
The best study to evaluate nerve injury is emg/ncs - nerve conduction study. These are preformed by a neurologist. It involves placing small needles and passing a small amount of current through them.
Good luck. ...Read more

Nerve damage: Can be detected via electrical studies such as electromyogram and nerve conduction studies. Under certain conditions, nerve biopsy can aid in the etiology. ...Read more
No easy answer: Depends on what the cause of your nerve damage, your other health issues if any, and your functional status (disabled or just chronic discomfort). Be sure you get an evaluation by a board certified neurologist and possibly a chronic pain specialist if pain is a major part of your condition. If there is an underlying condition causing it, that should be addressed as well (such as diabetes). ...Read more
There are many answe: Nerve damage can occur in many different ways. Some of the most common are trauma (injuries), arthritis or disk deterioration causing pressure on a nerve, compression neuropathy such as carpal tunnel syndrome in which a nerve going through a narrow canal is pinched or compressed, exposure to toxins (such as alcohol, chemicals and medication) and many diseases such as diabetes and thyroid. ...Read more
I always feel something crawling on me. Could this be a medical matter? For example, nerve damage?
Possibly nerves: See you doctor and have a neurological examination. ...Read more
I think I have nerve damage but when I went to get checked out they said it was just hyper sensitive. What's the difference between the two?
Not usually: Am amgiogram should not usually cause any nerve damage. Since to perform an angiogram, one must access an a rtery there can be temporary discomfort while this is accessed. Rarely, while numbing or accessing the artery, the nerve can injured. This is usually transient and very rarely causes permanent discomfort. ...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
