i try to walk as many days as possible. i also find that my feet are very sore and more painful after walking or standing for more than 15 minutes for that matter with an increase in numbness often. i keep doing it though unless im sick injured or in too much pain. i look at it as its not real what i am feeling it is how my brain is interpreting the messages from the damaged nerves or the lack of messages. not working through pain for injuries to me is something else entirely than working through pn pain.
