My feet are on fire


My mother f***ing feet are on fire at the end of every work day. They burn they are so sore and feel bruised. They ache for hours once I get home. I got compression socks, $90 insoles and I’ve been soaking them in a salt bath at night and still no relief. In the past 4 days I’ve worked 30 hours, standing 95% of that time. Anyone have any recommendations? I don’t know if I can make until November.
