Went to neurologist today and all he wanted was to do botox injections in the frozen neck and shoulder...questioned him about the new symptoms but he was not interested; so I paid for my test results and need help deciphering them

Findings: Sensory nerve action potentials and compound muscle action potentials were all normal in the left upper extremity. Concentric need EMG evaluation (all left sided) noted no spontaneous abnormalities at rest in any muscle tested. In the flexor carpi radialis, flexor digitorum sublimis, and to a lesser degree, the biceps, were seen myopathic-appearing motor units (low amplitude, polyphasic) and in some areas, continuous dense firing of MEPs. However, the degree of firing did seem to abate when I had the patient attempt to activate antagonist muscles. Continuous MUPs were seen in the sternocledomastoid. Needle study of the triceps and extensor carpi ulnaris were normal.

Conclusions: Abnormal study. The findings in this needle study were suggestive of a myopathy. In addition, there is evidence for continuous firing and generation of motor unit potentials that may be upper motor neuron or cerebrally initiated.

In prior EMGs, I have never had an abnormal EMG before so would like someone to help me understand the findings.
