Cold hands or color changes in the hands can occur due to conditions such as Raynaud phenomenon or may be related to environmental exposures. Irregular heartbeat is often a sign of heart rhythm disorders or arrhythmias. Joint pain can occur with many conditions and is a characteristic feature of the arthritis conditions. Pay attention to all your symptoms, and discuss any worrisome symptoms with a health care provider.
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 spasms of blood vessels, the cause is unknown. Symptoms and signs 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.
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.
Caffeine is a stimulant, which may be found in beverages, supplements, and medications. Common food sources include coffee, chocolate, green tea, and soft drinks. While caffeine addiction is not considered a real addiction, it can cause withdrawal symptoms, such as headache, tiredness, decreased energy, sleepiness, depressed mood, and more.
Premature Ventricular Contractions
Premature ventricular contractions (PVC) are premature heartbeats originating from the ventricles of the heart. PVCs are premature because they occur before the regular heartbeat. There are many causes of premature ventricular contractions to include: heart attack, high blood pressure, congestive heart failure, mitral valve prolapse, hypokalemia, hypoxia, medications, excess caffeine, drug abuse, and myocarditis.
