My podiatrist placed a stent in my left ankle a month ago because i have very flat feet. I had inflammation and alot of pain. Its been over a month and I still can t walk properly and it s still very stiff. I went back to the podiatrist and they did an xray and he told me that the stent he put in my ankle turned out to be too big for my ankle and it caused my joint in my foot to lock up. He said he needs to go back in and put a smaller stent in.
