Raynaud’s Phenomenon

Raynaud’s Phenomenon is a reduction of blood flow to fingers, toes, and nipples which occurs mainly because of cold, and causes extreme pain. 

Over the past few weeks, I have written articles about blood pressure and the medications used to treat this condition. Within these articles I mentioned that betablockers may be the cause of Raynaud’s and calcium channel blockers may help in the treatment. 

Interesting over the past couple of weeks, I have had two people come into the Dalby Chemist and ask about Raynaud’s, these people had not read my articles. 

An attack of Raynaud’s can be triggered by cold, like going out into the cold mornings we have had recently or putting your hands into chilly water. Occasionally there can be an emotional component as well. Typically, the fingers will turn white, and become numb. On rewarming will turn blue then bright red and swell. 

The cause of Raynaud’s can be from medication, connective tissue disease, arterial disease, nerve damage, emotions, or occasionally occupation. 

Treatment will depend on the cause. If medication, then ceasing the medication may be an option or adding a medication that has the opposite effect. Cease smoking because this impairs circulation. Keeping warm by wearing gloves, and socks. Swinging the arms around may increase circulations in the hands and fingers. 

Nicotinic Acid (vit B3) can have a dilating effect on the blood vessels, and there is an ointment available over the counter, used for a completely different purpose that may also be helpful. 

So, until next time keep well, come in and have a chat, your good health could depend on it.
