Nerve Conduction Test Side Effects
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
Risk vs benefits: Infection is the #1 risk which is less than 4% per 2004 study in journal neurosurgery spine. Less common risks include bleeding, nerve irritation/damage, allergic reaction, hardware malfunction, pain at implant site, dysesthesias, and spinal headache. The risks are fairly low in the hands of an experienced physician, and the benefits can be great. Talk to your doc about details. ...Read more
Pinched lumbar nerves. Any negative side effects to long term mechanized traction to relieve pinch nerve?
No, not Realy: As long as mechanical stretch gives you productive hours in your day, it is a good technique. If you forgo stretch of your legs, conditioning and strengthening exercise you will not achieve full recovery. When you know you have bad discs, avoid prolonged sitting, driving, and jarring sports which lead to chronic facet problems (arthritis) in the back. Inversion techniques / yoga mimic traction. ...Read moreSee 2 more doctor answers
Disagree with Rx: First, not clear to me if you possess a VNS device, but removal can increase sz frequency. Furthermore, you are taking too many seizure meds, as after the first two, the benefit of the third is NO MORE than 3-4% improvement at best and the 4th is clearly egregious. You are best served by either surgery or the VNS unit, and you need to see an epilepsy specialist to get some direction here. ...Read more
Disagree with Rx: Why hasn't the stimulator been replaced, as the newer versions have better batteries and are far smaller? Usually cough occurs when VNS settings too aggressively set, not when removed. Removal may result in increased seizures, and maybe your cough is part of a partial seizure. Have you discussed this with your neurologist?? ...Read more
No superpowers: Unlike comic books, no positive effects from brain trauma, spider bites, or radiation exposure. The only positive thing that i can even postulate is that you didn't die and that it should be a wake-up call if you are at high risk--drinking alcohol, not wearing seatbelts, not wearing motorcycle helmet, etc. ...Read moreSee 1 more doctor answer
Could taking lyrica (pregabalin) affect the results of an mr neurography study?
Brachial plexus neuropathy...
Good Question: This is a great question. I have not been able to find any research suggesting that Lyrica (pregabalin) could affect the results of an mr neurogram. Mr neurograms are relatively new, so i'm sure more information on this will become available soon. ...Read moreSee 1 more doctor answer
Severe paresthesia in extremities. Negative for MS (brain and spinal MRIs), negative EMG & NCS. On Lyrica (pregabalin) & Cymbalta but no relief. Recommendations?
More info req'd: It sounds like you've had a complex Neurological work-up and are intereted in seeking a second opinion. I would be glad to help, yet would need to see more data before throwing a diagnostic assumption at you. Please gather your medical records (labs/imaging/etc) and schedule a virtual consult with me for further details. I'm interested and available. ...Read moreSee 1 more doctor answer
Does nerve conductive study and emg prove nerve damage or nerve pain like sciatica? Can you have sciatic pain and normal results ftom these tests
Shows function loss: Emg and nerve conduction studies are very good at detecting nerves that have been damaged to the point where the nerves are losing function, but are not always sensitive to less severe damage that is causing nerve irritation without loss of function, or to disease elsewhere in the body, such as in the brain or spinal cord. ...Read moreSee 3 more doctor answers
dizziness and pain. : Usually not. However, a sudden sharp pain by nerve acute irritated might induce dizziness due to pain induced blood pressure disturbance. Most case pain medications, especially narcotics and nerve membrane stabilizers, such as Neurontin (gabapentin) might induced dizziness like feeling. ...Read moreSee 1 more doctor answer
Test nerve function: They are a way to test the function of nerves in the body, looking for focal (like carpal tunnel) or generalized (like diabetic neuropathy) problems. They are performed by stimulating the nerve electrically (which feels like touching a doorknob after shuffling your feet on a carpet on a dry day), and recording the response. They are uncomfortable, but very helpful in clarifying a diagnosis. ...Read moreSee 1 more doctor answer
I'm having nerve conduction tests for carpal tunnel. Couldl the same test show guyons tunnel syndrome?
Possibly: Depends on how detailed the neurologist or other physician is in performing the emg/ncv's. If your referring physician explains the need for testing the ulnar nerve in guyon's canal it can be done... In my experience most ' routine' EMG 's of the upper extremity will note conduction 'slowing' @ the elbow( cubital tunnel) but not @ the wrist... Best of luck! ...Read more
Can you have peripheral neuropathy with negative nerve. Conduction tests? Tested positive for bilateral carpal tunnel
Carpal tunnel or PN: If your nerve conduction test showed you have carpal tunnel syndrome, that is your diagnosis. Your nerve conduction test is not normal or negative if this is the diagnosis. This is a good test for distinguishing these two conditions. It is possible to have rare kinds of neuropathy with a normal nerve conduction test- this is why it is important to have an interview and exam with the test minder ...Read moreSee 3 more doctor answers
Microtubules!: Vincristine stops the formation of microtubules, which are important in cell division (leading to nausea, low blood counts, hair loss, etc.) but microtubules ALSO transport chemicals inside our nerve cells. The longest nerves in our body connect our spinal cord to our fingertips and toes ; this is why vincristine causes nerve problems especially in fingertips and toes. ...Read more
None by itself: This is a fairly minor change in the electrical pattern of the heart which is harmless by itself but you need to know if it's related to any heart condition. Some people have it from birth with no consequences. If it comes later from a heart condition or even hypertension, it may mean that the wiring system is starting to get tired & it will be checked periodically to make sure it's stable. ...Read moreSee 2 more doctor answers
What possible side effects could radiofrequency ablation have when done on lower back nerves without anesthesia?
Radiofrequency Ablat: More side effects from anethesia. The main side effect of radiofrequency ablation is some discomfort, including swelling & bruising at the treatment site that usually goes away after a few days. Leg numbness may develop due to the local anesthesia given during the procedure. It should only last a few hours. Mild back discomfort can occur as the local anesthetic wears off & typically lasts 2-3 days ...Read more
