Calcaneal apophysitis (Sever’s disease) is defined as an irritation and inflammation of the growth plate (apophysis) at the back of the heel bone (calcaneus) in bones with “open” growth plates = children and adolescents. Symptoms usually improve after it closes, typically around ages 14-16. HOWEVER, in an athlete with closed growth plates, this can present as achilles tendon irritation, so take some caution with “just waiting” it out.
It is pretty darn common in athletes that run a lot (soccer, track, xc, etc.), undergo repetitive lower extremity impact (gymnasts), have high volumes of training, train year-round in 1 sport, and are going through or just have gone through a growth spurt.
It’s a VERY manageable issue and rarely leads to worse injury, from my experience. If they have to take some time off of their sport, these athletes usually get back to activity quickly!
