Athlete's foot has accomplished an impressive feat.

​It's radiated from a rare condition to one lurking in almost every slipper. The fungus now infects 1 in 5 of the world's population. 

Anyone can get the itchy rash, from swimmers to care home residents.

And if it reaches your nails, well then you do have a problem. ​

I love curing corns. It gives instant agony relief.

Someone who hobbled along 20 minutes ago — suddenly walks with a spring in their step.

Well, you requested, I delivered. ​Here's why corns hurt so much
