De Quervain's tenosynovitis...thats what I used it for. I had a case of a sprained wrist turning into De Quervain's tenosynovitis..which is so painful and debilitating and I had tried everything! It started back in April slowly coming on until one day I couldn't do anything with my right hand. I couldn't bend my wrist in any way, without excruciating pain, my thumb couldn't spread out or have pressure of any type, I bought every type of wrist gadget, thumb gadget, tapes, had x-rays, had acupuncture for weeks (which is my go-to for any pain) , and nothing was working. Even sleeping at night was unrestful. I couldn't clean, pick up groceries, brushing my teeth I had to learn how to do that left handed!. I saw this after reading up on different red light therapy devices and thought I would give it it try. I started off by using a massager on my upper wrist area for about 15 minutes and then the light therapy device after for the whole time (30 mins) twice a day. I also used warm compresses and kept a wrist stabilizer most of the day and especially at night kept it on. I did this for about a week diligently while I watched TV or before I got ready for bed.After a week I realized I no longer had that shooting pain when I would accidently bang my thumb or wrist and after cutting back to using the device to once a day now, my pain is all but gone and I have flexibility in my wrist and thumb. I can even say that I had a few age spots on my hands that i can't even notice anymore, which is an extra plus!I never write reviews, ever, but I had to for this...it took a few weeks but if you're in pain use this device and it will definitely get you back to healing.
