I'm a cheerleader at my high school and yesterday we had cheer practice so I put a sports bra on to practice in and when I got home I was so tired I fell asleep with the sports bra on all night. When I woke up my shoulders were really sore. I realized then that I had the sports bra on so I took it off. Then I went to go look in the mirror and the sports bra caused a strange rash on each shoulder..there's a red mark with a bunch of tiny white bumps and it stings when I touch it. Is there anything I can use to sooth them and make them go away?
