Like heart attack, Raynaud’s is an attack. There are two main types of Raynaud’s: Primary&Secondary. In both types of Raynaud's, even mild or brief changes in temperature can cause Raynaud's attacks. It’s very important to keep feet warm to prevent an attack.During a Raynaud's attack, the arteries become very narrow for a brief period. As a result, little or no blood flows to affected body parts. This may cause these areas to turn pale or white and then blue, Feel numb, cold, or painful& a feeling of being pricked by pins and needles.Raynaud's attacks can last less than a minute or as long as several hours. Attacks can occur daily or weekly. Attacks often begin in one finger or toe and move to other fingers or toes. Sometimes only one or two fingers or toes are affected. Different areas may be affected at different times.
Diabetes and cold feet go hand in hand. In most cases of patients with diabetes that complain of 'cold feet', it can be attributed to one of two causes, vascular insufficiency or diabetic neuropathy. Diabetic peripheral neuropathy, sometimes known as DPN, is one of the most common underlying problems that lead to cold feet. It can also lead to tingling, burning, sharp pains or cramps, sensitivity to touch or numbness of the feet. Patient’s feet might seem warm to the touch, but they feel cold to them. The symptoms might be much worse at night.
Chilblains are the result of an abnormal reaction to the cold. When the skin is cold, blood vessels near its surface get narrower. If the skin is then exposed to heat, the blood vessels become wider. If this happens too quickly, blood can leak into the surrounding tissue. This is thought to be the reason for the swelling and itchiness associated with chilblains. Chilblains can occur at any age, but are more common in children and elderly people. The condition also affects women more than men. Certain people, such as people with poor circulation, are more susceptible to the condition
