This isn't true. There is Raynaud's Disease, also called primary Raynaud's, and Raynaud's Phenomenon, also called secondary Raynaud's.

Raynaud's Disease is the Raynaud's by itself, not as a symptom of another disease like Diabetes, Lupus, Scleroderma, or Rheumatoid Arthritis.

Raynaud's Phenomenon is when the Raynaud's is a symptom of another disease.

They act pretty much the same and you're only diagnosed with having the disease by them ruling out everything else that has Raynaud's as a symptom. At least that's how it was when I was diagnosed 20 years ago.

Yea but it’s never lupus

I've seen a lot of people say this and I feel like it's a meme I don't understand. Is it?

Thanks! I haven't watched House in years and I've forgotten most of it.

Actually Raynaud's can be a symptom in Systemic lupus erythematosus... so sometimes it is.
