Stubborn wart on my little toe treated today by my determatologist by freezing and applied cantharidin. but in so much pain can't walk! what to do?

Go home: Go home, remove your shoes and socks, elevate your leg on pillows, take analgesics. The pain will subside if you can avoid further aggravation. Good luck.

Wart or corn??: It is very possible your 'wart, ' is actually a corn (which is a callous usually from a result of an orthopedic consideration such as a bone spur or crooked toe), whereas a 'wart' is skin problem. Consider this and see your local area podiatrist. If it is a corn, you can put all the acids you want on it and it's never going to go away. You'd be treating a skin reaction verses skin problem.
