blueandinpain,
Radiculopathy is not a specific condition, but rather a description of a problem in which one or more nerves are affected and do not work properly (a neuropathy). This can result in pain (radicular pain), weakness, numbness, or difficulty controlling specific muscles.
In a radiculopathy, the problem is at or near the root of the nerve, along the spine. However, the pain or other symptoms may manifest in an extremity through a process called referred pain. For example, a nerve root impingement in the neck can produce pain and weakness in the forearm or hand.
Atrophy is a wasting of a tissue. In this case it would be muscle tissue. The reason being (neurogenic), when the muscle does not get signals from its nerve, it does not contract and work properly, so it wastes away. It is listed as mild, so the symptoms of weakness may not be significant.
You must have had more than one of these tests. Since evolution is determined by sequential testing. It states that your condition is static, not changing.
As to what can be done, that depends upon your physical exam and deficits. You really need to see a neurologist, discuss the test results, and determine your options.
Good luck.
