Raynaud's

Also called Raynaud's phenomenon, Raynaud's disease, or Raynaud's syndrome

Raynaud's is a common condition where the blood vessels in the fingers and toes narrow too much in response to cold or stress. The skin may turn white, then blue or purple, then red as blood flow returns. Most cases have no underlying cause (primary Raynaud's), but sometimes it is linked to conditions such as scleroderma or lupus (secondary Raynaud's).

What it is

Keeping warm, wearing gloves and warm socks, stopping smoking and managing stress help most people.

If symptoms are severe, medicines that widen the blood vessels may be offered. Secondary Raynaud's needs checking and treatment of the underlying cause.

Common signs

  • Fingers or toes turning white, blue or purple, then red
  • Coldness, numbness or pins and needles
  • Pain or throbbing as blood flow returns
  • Attacks lasting minutes to hours

How it is usually diagnosed

  • Questions about symptoms
  • Blood tests to look for related conditions
  • Sometimes nailfold capillaroscopy

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Blood test results
  • Rheumatology or GP letters
  • Medicine lists

Questions to ask your doctor

  • Could my Raynaud's be linked to another condition?
  • What can I do to prevent attacks?
  • Would medicine help me?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sores, ulcers or blackened skin on the fingers or toes: get urgent help the same day
