RAYNAUD'S disease is a condition that affects your circulation — and can leave you with discoloured fingers and toes.

TV host Jenni Falconer suffers from Raynaud's and posted a startling snap of her white finger. Here's what we know about the condition.

What is Raynaud's disease?

Raynaud's disease is a problem with your circulation that results in discoloured fingers or toes.

It is common and doesn't usually cause any severe problems — bit it can sometimes be a sign of something more serious.

You can often treat the symptoms yourself by keeping warm.

Symptoms include:

• pain
• numbness
• pins and needles
• difficulty moving the affected area

Some people also find their ears, nose, lips or nipples are affected.

The symptoms of Raynaud's may last from a few minutes to a few hours.

You should see a doctor if the problem is persistent or getting worse.

Also, numbness on one side of the body, joint pain, rashes, or if you're getting symptoms for the first time over 30 you should see a doctor.

What treatments are available?

Some people need to take nifedipine every day.

Others only use it to prevent Raynaud's – for example, during cold weather.

Sometimes your GP will examine you and suggest a blood test.

In rare cases, Raynaud's could be a sign of a more serious condition, such as rheumatoid arthritis or lupus.
