I had to buy a foot support for when I sleep at night. I've been dealing with a heel spur since grace was born. My dr said that most will heal by itself with 12-18 months. I've had two steroid shots so far. The first one was great. The pain completely went away until the shot wore off. The second one helped but not as well. My dr likes to hold off on the third shot incase it gets really bad. So when I went in this time he suggested the foot support. Apparently my ligament grows back between my arch every night but when I get up in the morning if I forget to stretch it before getting out of bed, it tears it and causes inflammation and pain. Also my foot doesn't stay at a 90 degree angle over night so that causes the ligament to grow back to short. So this is supposed to keep my foot at the right angle. I hope it helps. I'm ready to have my foot back.
