I stand at work all day and at the end of the day, my feet is in so much pain. can you help me in minimize this pain?

Need more info: May need to see a Podiatrist.Where are your feet hurting-middle bottom to heels-may be plantar fasciitis-if so freeze two water bottles and roll feet back and forth several times a day and take some ibuprofen.You may need inserts if all over especially if have flat feet.Many people have foot pain from wearing steel toe boots and inserts and scool compressses at end of day with ibuprofen may help.

Agree with Dr. K: In addition to the advice by Dr. K, you should talk to your supervisor as it may be covered by OSHA and your work place may/could provide a better work environment, Your schedule could be adjusted so that you may take short breaks to sit down. Having a padded mat to stand on may help too.
