Someone stepped on my foot last night the inside of my R foot has pressure/pain when I walk on it. Swollen& red spot where it hurts could it b broken?

Watch that step. Right now , the best thing to do is get your foot RICED. Rest it. Ice it. Compress it lightly. Elevate it. Get to a Dr. and get it evaluated if it does not improve by tomorrow. Probably just soft tissue damage, but without an x-ray it is difficult to tell.
Certainly. possible, make sure to ice it as much as possible..
