I just started a new retail job where I m standing for eight hours at a time. I stretch a few times each day, wear proper shoes, etc but have noticed by the end of the day my legs become extremely painful. And I ve also noticed bruises that are along the outer side of my legs, from my knees up to my but cheeks. I ve tried ipuprophen, ice, etc but still end up in pain at the end of the day. Help please!
