10 Years ago i was wrongfully diagnosed with Tendonitis in both ankles and sever flexible flat feet. 10 years later and i now have my own health insurance, (because i couldn't afford it otherwise) i go see yet another doctor to see what is really going on. Now keep in mind that for the past ten years i have had sever painafter an 8 hour day at work. I have had to call in to work "sick" because i couldn't walk the next day. Now this doctor says i dont have tedonitis or flexible flat feet but i have ridged flat feet and something about a sinus tarsi (which can be operated on and fixed within a day). i have lived like this for ten years, but it can be fixed in one day!!!
