Dear MJD22:
Sorry that your having problems with your fingers and toes. First, this is not ALS, not ALS as you do not have muscle weakness without any sensory changes. T2 and T3 are low in the cord to be having symptoms in the finger tips. I am not sure what might be causing your symptoms as the differential diagnosis (things that could cause your symptoms) is very large. I would see a neurologist and get a good neurological exam and have some basic lab test performed. From these the possibilities will be narrowed and further testing can be more directed. I hope that things are benign.
Sincerely,
CCF Neuro MD
