Symptoms of thoracic cord compression include imbalance, loss of fine motor control in the lower extremities and bowel/bladder dysfunction. By your description, I do not think you have most of these symptoms.
In addition, cord compression leads to long tract signs. These are signs found upon physical examination that include hyperreflexia, clonus, dysesthesias and problems with gait seen with stress maneuvers. A spine expert should be quite familiar with these signs and should be able to identify them. If these signs are absent, there is more evidence that you do not have myelopathy (dysfunction of the cord due to compression).
Muscle fasciculations that occur “all over” your body are not related to the spinal cord. There are many different conditions that can cause these fasciculations and a metabolic work-up might be helpful.
