Has anyone had De Quervain's tendonitis. I developed it all of a sudden and now its really bad in both wrists. Had injection for left hand and go back for the right in 2 weeks (i am right handed). I don't understand why I have it. I have been waking at night over past couple years with painful elbows, but nothing during day. I'm wondering if I have something else going on, or could this be related to chiari somehow? It is quite painful and on top of everything with the chiari I don't feel like I can handle this right now. Any advice would be appreciated. From what i've read this tendonitis is common, so maybe someone here has had it, did it get better? I also go to PT this week. The injection didn't help much at all. Using topical steroid cream too, trying everything, ice etc.
