Apart from the corn
cap you need a change in your footwear to ensure that pressure is relieved from the area where the corn is present during walking otherwise the corn would re form. If the corn does not respond to application with corn cap for another couple of days then you can go to a surgeon and get that surgically removed. This can cause quite a bit of pain in the postoperative period but it removes the "root" of the corn and can be quite successful as a therapy. However, prevention of recurrence using the customized footwear is the most important part.
