I work at a sports complex. We have a skatepark, so we constantly fall and bruise and scream in pain. There was such a case: a 13-year-old boy, riding a scooter, jumped onto the railing, they have such an obstacle. Something didn’t work out for him and, falling, he broke his periosteum from his knee to his ankle. The whole stadium screamed, he was white as snow when I put FSC No. 2 on his leg. About 20 minutes passed. The pain subsided, even the children noticed how their faces turned red and the blood stopped flowing. About 10 days later he came back to ride - his leg didn’t hurt. Thanked me for my help. I always carry FSC No. 2 with me. He helped me more than once.
