then the tinosynovitis is a subset of that where we have these effectively water type tubes specifically in our flexor tendons and those tendons are gliding beautifully in there there's a little bit of fluid our body produces to keep them gliding smoothly and a little bit of what we call Tina synovium which is just a filmy structure that gives them some lubricating tefloni feel if that gets inflamed from overuse whether you're a violinist or a heavy weight lifter doing all sorts of things over and over again you can develop inflammation there and then that becomes trapped in there and it really hurts it can eliminate mobility and it can even cause them sometimes to lock down and those are super common and we can often cure them with just cortisone shots or rest or both but then ultimately a subset of them because they're so ubiquitous requires surgery which is very minor but it's important because the hand function if you have one finger that's really stiff whether you dislocated it or even just sprained it the other fingers they're all linked so indelibly together that actually it will make your whole hand feel stiff
