This is not typical of a pinched nerve in the neck , or a stroke as you describe it. Possible, you are not prescribing neck problems or the radiculopathy that normally occurs, and the lack of coordination would not be typical.
It is consistent with neuropathy and diabetes is one of the most common causes.
B12 is unlikely as well with this presentation.
Heavy metal toxicity acts like this.
liver or kidney disease can cause this type of symptom.
alcohol and other symptoms.
The poor coordination is concerning, and although rare, even MS could start like this.
You can start with an internist....in most cases, that will get the diagnosis, and neuologists usually need a referral.
OK, so that is an initial answer….
