Raynaud's phenomenon describes when your extremities feel cold, numb and change colors often in response to a sudden temperature shift like grabbing a cold glass of water. It commonly affects the fingers and toes. It is due to a sudden decrease in blood flow to those parts of the body. It may occur in isolation and it may also occur as a symptom of systemic disease.
Seek professional care if you experience any of the following symptoms
Generally, Raynaud's phenomenon can be related to:
This disorder of unknown origin causes decreased blood flow to the fingers due to blood vessel spasms. Initially, fingers turn pale when exposed to cold, then become swollen, painful, and red when warmed.
Mixed connective tissue disease (MCTD) is a rare autoimmune disorder where the immune system mistakenly attacks the body's own tissues. Risk factors include family history of connective tissue disease and exposure to certain viruses or chemicals. It's most common in women in their 20s and 30s, but children may also be affected.
Scleroderma is a connective tissue disorder that causes the skin to thicken and harden, though it may also affect other organs. It is categorized as localized or widespread (systemic scleroderma). It is a disorder where the immune system mistakenly attacks its own body.

My experience was great. I was worried, but the symptom checker helped me narrow down what it might be. I feel a little relieved compared to when I first started, and it gives me a starting point for what my symptoms could mean.

Female, 40s
I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
