I just call it "half-numb"!
I don't think neurologists or other doctors expect (or even want) patients to come in using "proper" terminology. They want you to DESCRIBE your symptoms the way they feel to you. There is no "right" or "correct" way to describe them. You serve yourself best if you don't try to shoehorn your symptoms into terminology you've learned, but rather to describe them in everyday terms.
Take care, doydie!
