Re: Gymnastics injury
seems like you're n active person being in gymnastics.. maybe take some anti inflammatories apply some icyhot and give it a few days. If it gets unbearable hit the ER if it is the same for a few days call the doc and make an appointment.
As a gymnast I'm sure you know a lot of good stretches try to maybe apply some stretching to it. When doing that if it makes it worse quit right away.
Follow your body though, if it hurts a lot seek medical attention asap..
