I have had a corn removed 2 times from the side of my heel, i've changed shoes, however, it is turned white and is swollen and extremely painful, i cannot walk on it, the wound is still open as the dr went deep to get the core and the skin outside it is puffy and firm, its been 2 weeks since i had it done, i hate going back because it hurts so much, i'm dreading anything touching it, including a needle
