The expert shared the different symptoms to look out for – and when to see a doctor
A doctor is warning anyone whose hands and feet change colour in the cold may have a serious health condition. There are a number of other symptoms the doctor says to keep an eye out for to.
The condition, Raynaud’s, can cause some areas of the body such as your fingers and toes to feel numb and cold in response to cold temperatures or stress. Doctor O’Donovan, who has a medical degree (MBBS), Masters Degree (MRes) in Ageing and Health, and PhD (DPhil) in Digital Education, shares information and advice with his almost 400k subscribers on YouTube.
In a recent video, he explained they symptoms of Raynaud’s and when you should seek medical help. He said: “In Raynaud’s disease the smaller arteries that supply blood to the skin narrow in response to triggers like cold weather this limits blood flow to the affected areas which is called vasospasm and it then results in symptoms of Raynaud’s.
“Over time the small arteries can thicken slightly and it can further limit blood flow even more.”
Discussing symptoms, he added: “In terms of signs and symptoms, the first thing that you’re likely to notice are the areas of your skin can turn white then blue but depending on your skin colour. These colour changes may be harder or easier to see, you may also notice that you’ve got particularly cold fingers or toes or you might notice other changes in the sensation of your hands or feet so things like a numb, prickly feeling or stinging pain.
“Now when the skin warms and blood flow improves the affected areas may change colour again they may throb tingle or swell. Whilst it most commonly affects fingers and toes it can actually affect other areas of the body so things like the nose the lips and ears. Now even after you’ve warmed up it can take up to 15 minutes for blood flow to return to the area.”
According to the doctor, experts “don’t fully understand” the cause of Raynaud’s attacks but “blood vessels in the hands and feet appear to react too strongly to cold temperatures or stress.” He added that cold temperatures are actually the “most likely” cause of an attack, using examples like putting hands in cold water, taking something from a freezer or being in cold air. He claimed that, for some people, emotional stress can also trigger an episode.
Doctor O’Donovan said: “You should see your doctor if you have symptoms of Raynaud’s that are very bad or getting worse, the Raynaud’s is affecting your daily life, your symptoms are only on one side of the body, you also have joint pains, skin rashes or muscle weaknesses.”
The doctor also says to see a doctor if “you’re over 30 years old and get symptoms of Raynaud’s for the first time, or your child is under 12 years old and has symptoms of Raynaud’s.”
