This is my two cents.....no one but you knows your level of pain with standing.....my share is this; I had an injury, surgically, to my leg. I was prescribed leg braces....but haven't found the right fit....my leg/ foot would have the calf pain, curling toes, turnic feeling etc....one day years later....my ankle just broke...I was walking and I went down like a sack of potatoes. I never had the blocks etc.....why my ankle, which I was careful to rest etc when the pain was insane....I dunno.
Standing that long can cause a normal person problems....I just saw an article about sitting and or standing too long at the office cause health issues.
I can't walk long distances without feeling some weird weakness to sever pain.
You are at a cross road only you can walk. But knowledge is powerful. I wish I could say one way or the other
