Should i stop walking on my treadmill for a while?

I have a treadmill at home that I just got like 2 months ago and have been trying to get at least 10k steps a day sometimes more but recently I think I’ve been overworking myself because one of my feet hurts really bad and Ive been limping. I really like walking and don’t want to have to give it up (not permanently but just until my foot heals) I’ve still been doing it because after a while of walking it gets better, I pay for it the next day though. should I stop until my foot heals or is this just going to keep happening no matter what? And does anyone know how I prevent this?
