Last time I had it I learned about "Dr Archie, "a golf ball sized piece of rubber . It rolls under the arch and works perfectly. Now, years later, I found myself in the Caribbean with no Dr Archie and fire in my heel as I tried to hobble. Dr Google mentioned a frozen lime. Whoa. Pain gone in 20 minutes and no return. Frozen lime. Who knew? Just roll it around your arch and rejoin the living.
