Sometimes a section of a nerve is cut completely or damaged beyond repair. In these cases, your surgeon may enlarge the tight space or free the nerve from the scar. Sometimes a nerve sits inside a tight space (similar to a tunnel) or is squeezed by scarring. Doing an EMG test directly on the nerve is more accurate and reliable than doing the test over the skin.
If your injury does not seem to be healing properly, your surgeon can use EMG testing in the operating room to assess whether scarred nerves are recovering. Your surgeon can bypass a damaged section of nerve by connecting a healthy nerve to restore function. Your doctor may recommend physical therapy to prevent stiffness and restore function.In some cases, you may need corticosteroid injections for pain relief. Medications used to treat depression, seizures or insomnia may be used to relieve nerve pain. Depending on the type and severity of your nerve injury, you may need medications such as aspirin or ibuprofen (Advil, Motrin IB, others) to relieve your pain.If your injury is caused by a medical condition, your doctor will treat the underlying condition.You'll need regular checkups to make sure your recovery stays on track.Nerves recover slowly, and maximal recovery may take many months or several years. You may need to rest the affected area until it's healed. If your nerve is healing properly, you may not need surgery.Your doctor will determine your treatment based on the extent and cause of your injury and how well the nerve is healing. Injuries in which the nerve has been completely severed are very difficult to treat, and recovery may not be possible. When he did my hand, I was very aware that a needle was involved.If a nerve is injured but not cut, the injury is more likely to heal. That was the first I knew that the EMG involved needles! Sometimes ignorance is advantageous He said, no, he had a needle in my arm and was repositioning it (without pulling it all the way out). I asked the doctor if he had applied tape and was pulling on it. I was laying on the table almost asleep and felt some tugging on my arm's skin. For my first EMG, I did not know that the test involved needles. In my case, the subject EMG was performed on one side of my body about 1 week before the muscle biopsy was performed on the other side of my body. When they did the muscle biopsy, they told me that it would take some time (I believe several weeks) for things to recover sufficiently from the EMG for the biopsy to produce meaningful results. I generally felt OK right after the tests, though some of the muscles they spent extra time on were a bit crampy and sore for a day or two.
