I'll admit I picked up the Tendlite with a bit of skepticism. Although I've heard great things about light therapy in the past, I've always stuck to the meds. After a GLOWING review (pun intended) from my co-worker, I just had to try the Tendlite for my carpal tunnel. My pain killers were losing their effectiveness and the subsequent upset stomach was just not worth it. To my surprise, this product is a wonderful relief! I love it and highly recommend it to anyone going through this with me!
