For those of you lucky enough not to know what it is, Raynaud’s is a phenomenon in which the small blood vessels of the hands, feet, and or tip of the nose “overreact” to cold temperatures and cause excessive narrowing and therefore restriction of the blood flow. This can then cause the extremity to become 1) white due to lack of blood flow, then 2) blue due to cyanosis (lack of oxygen in the blood in that area), then 3) red when the blood flow returns. It is an uncomfortable problem that causes numbness to the area, and pain and tingling when rewarmed (kind of like when your toes get too cold in the snow and it hurts to rewarm them). Raynaud’s can be primary (due to unknown causes) or secondary to other diseases (such as lupus, RA, scleroderma, carpal tunnel syndrome and others) and may be autoimmune in nature.
Much of the time, Raynaud’s is an annoyance without too much of a long term problem; however, if you are unlucky enough to have Raynaud’s and POTS together, you also have the problem of (usually) being put on beta blockers, which almost always make the problem of constriction of those blood vessels much, much worse. I had mild Raynaud’s prior to POTS, but after taking beta blockers to help with POTS, my Raynaud’s has become quite severe, especially in my toes. I was off of the beta blockers for a while, and it seems that my Raynaud’s is still pretty bad without them now, but much worse on them. Because my toes are so sensitive to any temperature change, I have to wear wool socks all year round, yes including summer (!) because otherwise the blood flow to my toes completely stops and is slow to return so I run the risk of developing ulcers without warming and massaging the blood back into the area. Here’s an example of my toes in the middle of the summer at the beach (ie it’s like 90 degrees out):
- Keeping warm: Unfortunately, many of us need to wear gloves and wool socks to keep warm enough to keep from triggering an “attack”. As I mentioned above, I wear wool socks 365 days a year to prevent the very unpleasant attacks. It can also be helpful during the winter to keep toe warming packets on hand in case of severe attacks (I keep them in my purse). I also purchased a paraffin bath a few years ago, and that can be nice because it is warm and sort of “cocoons” your hand or foot to keep it warm (I’ve never used it during an acute attack though, just with mildly cold hands or feet, and the container is kind of big, and you have to keep it heated for the wax to stay liquid). I also always wear socks to bed, and have even worn thin gloves to bed when I’m really having flare ups.
- Reduce stress: stress has been linked to an increased frequency of attacks
- Avoid smoking- it’s been linked to an increase in constriction of vessels, therefore an increase in attacks
- Reduce caffeine (I have to admit, I haven’t been able to try this one because I love my morning coffee!) as it has also been linked to increased vasoconstriction
- Some drugs can worsen Raynaud’s, such as beta blockers, some migraine meds, some chemotherapeutic drugs, some over-the-counter cold medications and narcotics…drugs that cause vasoconstriction.
- There are also some medications that may help with severe Raynaud’s, but are usually not required (see your doctor if you think you might need this kind of prescription)
- I find that warming the area is the most important first step. Try to place the hand or foot in a warm area (under your arm, knee, sit on them, whatever it takes!) I usually will try to massage the area to get the blood flowing again, which will eventually help it warm and improve. If it’s really severe, you might want to submerge the area in warm (not hot) water to rewarm the area. If the water is too hot, it will really hurt (think freezing cold hands in the snow then straight to hot water…not pleasant). If you can’t get the area to refill with blood after warming, it’s best to go to a doctor to make sure that you don’t run the risk of developing necrosis in the area, although that is rare.
