My beau is a type 2 diabetic. he had an episode where his right hand was having spasms and seemed to be paralyzed .

A # of possibilities: A transient episode of cramping and spasm can be something benign and no cause for concern, such as a reaction to overuse, an electrolyte imbalance or a medication side-effect. Without additional history or an exam i couldn't say whether its something more ominous such as impending stroke. Because of his risk factors he should she his pcp as soon as possible.

Stroke: How good is the diabetic control ? Does he smoke. What is his weight. If all these are good then it may have something to do with his neck. If he is a smoker, or overweight, or diabetes is not under good control then he needs to see his doctor asap. Diabetes is a multisystemic disease meaning it effects every system of a person's body, and he should be under care of a doctor and check blood sugar.
