I have a friend who had an operation on her leg due to cancer. She has recovered from this operation and goes to physical therapy. She walks with the help of a cane.
The problem she is having is severe toe cramps that really hurt her. She busted out in tears she was in so much pain while i was visiting her. It there something perhaps that may be lacking in her diet. She does take a good muti-vitamin.

I would just pull on my toes, manipulate/massage them.
Make sure I ate a banana a day for potassium.
