Severs!!!!. My cp got it first when she was 7, it flared up each time she went through a growth spurt. You have to ice it as much as possible, and stretch the achilles. She wore heel cups for about a year and a half that helped. One thing that also helped, which I was skeptical about, but it did as it advertised was something called Oscon, available online. We constantly keep a supply of this and although its very rare now that shes 11 and 1/2, whenever she complains of her heel/heels hurting, usually after an intense tumble session, she takes two Oscon each day and in a few days pain is completely gone. We have been to so many orthopedic docs after orthopedic, and all wanna put her on crutches and sit her out for 6-8 weeks. Not possible in this sport. She found a way with ice, stretching, foot taping (KT Tape is awesome) and Oscon to help ease the discomfort and continue to cheer and tumble. Sorry to hear about your cp. But know it does go away completely when their growth plates fuse at around age 12. And my cps issues are pretty much gone now! Good Luck to you both!
