First off,: You should realize that a nerve conduction test doesn't offer accuracy of 100%. There are false negatives results. Mri's are tricky too. Particularly with certain nerve entrapments and who is reading them. Nerves generally don't cramp, muscles do. Tingling is usually nerve related. The nerve in your case i would look for is by the fibular head and/or in the back. A good physical exam is key. ...Read more

Nerve (Definition)

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

Should i possibly get a nerve conduction test?

Should i possibly get a nerve conduction test?

Depends: It really depends on what the possible problem is. Nerve conduction tests are usually done with electromyography. The test is non-invasive and an office procedure that does not require anesthesia. The electromyography portion involves needles. ...Read more

What does a normal emg/nerve conduction test tell you?

What does a normal emg/nerve conduction test tell you?

Interpretation: Assuming the test was comprehensive and technically competent, this can eliminate large fiber neuropathy, and most muscle diseases. But does not eliminate small fibre neuropathy, or disease of brain and/or spinal cord. Symptoms due to intermittent nerve compression are not fully excluded either. ...Read more

What can I expect from an emg, or nerve conduction test?

What can I expect from an emg, or nerve conduction test?

Tolerable discomfort: There are two parts to an EMG test: nerve conduction studies and electromyography. Nerve conduction studies feel like a short, electrical impulse and are, in a word, annoying. Emg uses a fine wire electrode to record from muscles and feels like an insect bite. It is not as bad as a shot or IV or blood draw. Several muscles and several nerves are usually checked. ...Read more

What is an emg and nerve conduction test for?

What is an emg and nerve conduction test for?

Nerves & muscles: Emg and nerve conduction studies are used to detect abnormalities of nerves and muscles. The test evaluates nerve roots as they exit your spine, the nerve plexus, peripheral nerves, the nerve-muscle junction, and muscle itself. It can detect pinched/compressed nerves (sciatica, carpal tunnel, and others), muscle disorders, neuropathy, and many other neuromuscular conditions. ...Read more

What to do if I have to have a nerve conduction test on my upper limbs in hospital?

What to do if I have to have a nerve conduction test on my upper limbs in hospital?

No preparation need: Your test will be done with mild electrical shocks, and recordings of the stimulation results. An EMG part will use small needles, and the greatest risk might be a small bruise. If done thoroughly and fully, answers for location and severity of nerve problem will be uncovered. ...Read more
