I ran through almost a 2 year battle in both wrists (flexer tendon) it was brutal, it was a direct effect of my job. I taped, wore boxing wraps to work, cortisone, relaxed, you name it, I was submersing my hands in hot water ( as hot as I could handle without burning myself ) for 3 min, then switching to ice water for 1 min, hurt like you wouldn't believe but got the blood flowing, do it as many times as you want a day. I felt like it made a big difference. I'm not sure what really ultimately fixed it but I'm thankful it's gone. I was in so much pain it would wake me from a dead sleep. Good luck!
