You can have primary or secondary Raynaud’s, and which type you have depends on the cause of your condition and the symptoms.
The Mayo Clinic explains that Primary Raynaud’s, also called Raynaud’s disease, is the most common form.
Primary Raynaud’s isn’t the result of an associated medical condition and can be so mild that many people don’t seek treatment as it resolves on its own.
Secondary Raynaud’s (Raynaud’s phenomenon), on the other hand, is caused by an underlying problem such as connective tissue diseases, artery diseases, carpal tunnel syndrome, injuries and certain medications, and this type tends to be more serious.
If secondary Raynaud’s is severe — which is rare — reduced blood flow to your fingers or toes could cause tissue damage and untreated cases might require removing the affected part of the body.
