De Quervain's tenosynovitis (duh-kare-VAHS ten-oh-sine-oh-VIE-tis) is a painful inflammation of the tendons on the thumb side of the wrist, and if you have it "you're likely to feel discomfort every time you turn your wrist, grasp anything or make a fist." I don't know if you've ever thought about just how many times a day (or even an hour) you "turn your wrist," but trust me - it is A LOT.
I've been dealing with this pain every time I move my right hand for weeks and I've tried everything I can think of to make the pain stop. I've iced my thumb and wrist. I've soaked my hand in cold water and hot water and Epsom salts. I've warmed my hand with paraffin. I've wrapped it, braced it, tried to use it as little as possible, tried to stretch it gently, taken anti-inflammatory and pain-killing drugs...all to pretty much no avail. So I finally caved and called my rheumatologist, and he diagnosed me with de-qu-whatitis-itis.
Also known as "washerwoman's sprain" or "mommy thumb," most people get de Quervain's tenosynovitis from repetitive hand or wrist movement - like washing clothes by hand or constantly picking up and carrying a baby. (Turns out it is also a lot more common in women, hence the sort of sexist nicknames). More recently, the syndrome has been dubbed "Blackberry Thumb" for people who get it from too much texting. (And one of my friends rather rudely suggested calling it "Handjobitis")
But I didn't do any type of repetitive motion to trigger this pain. Apparently (lucky me!) if you have RA, you can get de Quervain's tenosynovitis for absolutely no reason whatsoever!!!
RA you never cease to surprise me.
