Some symptoms of Raynaud's phenomenon include cold fingers or toes, color changes in affected areas and numbness or stinging pain upon warming. Raynaud's phenomenon is a condition that affects blood flow. The body fails to send adequate blood to the hands and feet, causing them to feel numb and cold, according to WebMD.
There are two types of Raynaud's disease, called primary and secondary Raynaud's. The actual cause of both types of Raynaud's are unknown, notes MedicineNet. Some of the conditions closely associated with Raynaud's phenomenon include trauma, rheumatoid arthritis, lupus and hypothyroidism.
Individuals with this condition experience cold fingers or toes during an attack. This is usually as a result of blood deprivation to these parts. During the attack, the patient may observe a change in color of the fingers due to lack of blood. The color change in affected areas is often blue or white. As the individual warms, the affected area is likely to turn reddish and a tingle or throb is experienced. In some cases, swelling may also occur.
To manage this condition, doctors usually encourage patients to avoid medications that may aggravate blood vessel spasms. Dressing up for the cold and wearing gloves is a good way to avoid cold attacks. Some medications may be prescribed by doctors.
