Corns on the Foot
This is probably the most common problem that is seen by podiatrists either for regular routine care or for surgical correction of the underlying problem that is causing the corn.
There is plenty that can be done to help this problem and plenty of online advice available (link). The best advice is anything that you can do to get pressure of the area that the corn is on will help with the symptoms. This means better fitting shoes with more room for the toes. It means the wearing of padding to straighten toes and relieve the pressure. Most important do not use the so-called corn cures as they do not work over the longer term. If this is not helping, then see a podiatrist. There is no point putting up with these.
