Epocrates
I’m sure there have been plenty of better ideas offered, but the one product I swear by are compression socks. I worked an average of 72 hours/week during Covid and my legs and feet were killing me until I started wearing compression socks. I also learned through a physical therapist to change shoes every six months, especially nurses working 12-hr shifts. I’m 5’7”, weigh around 140 lbs, and I swear by compression socks.
