Hey Barbara,
Wow, I can't even imagine standing for that many hours and days. I sure hope you aren't over doing it. If this is something new happening, you should call your neuro and fill him/her in. I too use to do so much on days I felt strong and then end up paying for it on the couch for sometimes days. Now I only do that once in a while...just isn't worth the price. Take care and let us know how you're doing.
Hugs,
Pat
