Home remedies??

I'm a baton twirler, and i have MAJOR bumps and bruises on my arms and hands is there anything I can do to soothe these? Especially broken blood vessels in my finger tips? Also, if you have any tips on how to soothe strained back, arm, and hips? I'm only 16 im not supposed to be falling apart yet. Pls help i have a game tomorrow night😂 Oh one more. I practiced barefooted on a dirty gym floor and rubbed the calluses on my feet raw? Fix me please😭😭😂😂
