I was a manager at Verizon Wireless store..so I was on my feet all day. In the stores chairs are not allowed and it has been a big issue with people.
My neuropathy worsened over the years until 8/08 where I lost total sensation in my feet and now the neuropathy has travelled to my legs and right arm causing weakness as well. My neurologist and kidney doctor are writing letters and filling out forms. The answers to one form my neurologist filled out are listed below.

I have a copy of the form
Lifting = up to 10 lbs occasionally up to 1/3
Carrying = up to 10 lbs never

At one Time
Sitting =less than 15 mins.
standing= less than 15 mins
