These symptoms can be present in a number of medical conditions. A change in skin color or temperature could be related to a circulation issue. If you are concerned about your symptoms, you should contact your doctor.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Raynaud's phenomenon is characterized by a pale-blue-red sequence of color changes of the digits, most commonly after exposure to cold. Occurring as a result of spasm of blood vessels, the cause is unknown. Symptoms of Raynaud's phenomenon depend on the severity, frequency, and duration of the blood vessel spasm. Treatments include protection of the digits, medications, and avoiding emotional stresses, smoking, cold temperature, and tools that vibrate the hands.
Peripheral Vascular Disease
Peripheral vascular disease (PVD) refers to diseases of the blood vessels (arteries and veins) located outside the heart and brain. While there are many causes of peripheral vascular disease, doctors commonly use the term peripheral vascular disease to refer to peripheral artery disease (peripheral arterial disease, PAD), a condition that develops when the arteries that supply blood to the internal organs, arms, and legs become completely or partially blocked as a result of atherosclerosis. Peripheral artery disease symptoms include intermittent leg pain while walking, leg pain at rest, numbness in the legs or feet, and poor wound healing in the legs or feet. Treatment for peripheral artery disease include lifestyle measures, medication, angioplasty, and surgery.
The common cold (viral upper respiratory tract infection) is a contagious illness that may be caused by various viruses. Symptoms include a stuffy nose, headache, cough, sore throat, and maybe a fever. Antibiotics have no effect upon the common cold, and there is no evidence that zinc and vitamin C are effective treatments.
There are two categories to cold weather-related injuries. 1) no freezing of body tissue (trench foot and chilblains), and 2) freezing of body tissues (frostbite). Chilblains in general, will not need medical attention (unless there is infection). Trench foot and frostbite, however, require medical attention. Symptoms of frostbite include pain, burning, numbness, and eventually a complete loss of sensation in the affected body part. The young, elderly, and patients with certain medical conditions (diabetes, hypothyroidism, circulatory problems, and psychiatric illnesses), are more susceptible to cold weather-related injuries. People who abuse alcohol and illicit drug user are also at risk for cold weather-related injuries.
