Electrodiagnostic testing that includes NCS & EMG can be very expensive, with prices ranging from $800-$2500. This type of testing can be very sensitive and useful to determining if there is a problem with a nerve, and if there is a problem, it can determine how bad that problem is.

Yes,you can but you shouldnt because pain killers will effect the nerve responses and make for inaccurate results. so just have your test and take your medicine after. If you have nerve damage youll need it more after the test anyhow.
Electromyography, a method of evaluating muscle function by detecting and measuring electrical activity in the muscle.
That would be the Projection
EMG is a method of measuring muscle activity. In a research laboratory where conditions can be controlled (such as location of electrodes, posture of subject, etc.) and the data can be analyzed accurately (normalized, etc) this can be a very useful tool. A small number of chiropractors feel that this tool can be used to detect areas of spastic or "tense" musculature, and thereby use it to help decide where to adjust the spine. The problem is that none of the strict controls or data analyzing techniques are applied in the clinical setting (doctors office), making this tool very inaccurate. Further, there have not been any studies done that examine the clinical relevance of this tool (no link has been shown between good "scans" and better health of a patient).
As a rule the more areas you need studied, the more the test will cost. However costs may vary from one physician to another and is different in different states. It is always best to inquire about cost with your physician. Most insurance policies cover EMGs, though frequently the coverage is not 100% and the primary care or insurance physician will have to OK it before it can be ordered. It is best to have your doctor's office find out what kind of coverage you have for an EMG.
Yes they are.

Morton's neuroma is a thickening of nerve tissue between the toes. It commonly affects the nerve that travels between the third and fourth toes.
See also: Foot pain
Causes, incidence, and risk factorsMorton's neuroma is more common in women than men.
The exact cause is unknown. However, some experts believe the following may play a role in the development of this condition:
Symptoms of Morton's neuroma include:
In rare cases, nerve pain occurs in the space between the second and third toes. This is not a common form of Morton's neuroma, but treatment is similar.
Signs and testsA foot x-ray may be done to rule out bone problems. MRI or high-resolution ultrasound can successfully diagnose Morton's neuroma.
Nerve testing (electromyography) cannot definitely diagnose Morton's neuroma, but may be used to rule out conditions that cause similar symptoms.
Your doctor may order blood tests to check for inflammation-related conditions, including certain forms of arthritis.
TreatmentNonsurgical treatment is tried first. Your doctor may recommend any of the following:
Anti-inflammatories and painkillers are not recommended for long-term treatment.
In some cases, surgery may be needed to remove the thickened tissue. This can help relieve pain and improve foot function. Numbness after surgery is permanent, but should not be painful.
Expectations (prognosis)Nonsurgical treatment does not always improve symptoms. Surgery to remove the thickened tissue is successful in about 85% of cases.
ComplicationsMorton's neuroma can make walking difficult. Persons with this foot condition may also have trouble performing activities that put pressure on the foot, such as pressing the gas pedal of an automobile. It may hurt to wear certain types of shoes, such as high-heels.
Calling your health care providerCall your health care provider if you have persistent pain or tingling in your foot or toe area.
PreventionAvoid ill-fitting shoes. Wear shoes with a wide toe box.

When discussing needle size we can look at two characteristics: length and diameter.
The length of the needle used can vary based upon the examiner's preference or how much tissue exists between the skin and the desired muscle for the doctor to examine. Most needles are usually around one and one half inches but the sizes tend to vary from 1-3 inches in length
The diameter of the needle is measured in gauges, with the larger the number of the gauge corresponding to a smaller diameter. Most needles used for EMGs range from 26 gauge to 30 gauge.
Most of the pain that occurs with any needle insertion is usually from the initial insertion of the needle through the skin. This reduced by the technique of the doctor, the gauge (or diameter) of the needle, and the shape of the tip of the needle.
During an EMG test, a fine needle is inserted into the muscle to be tested
