I have a hernia on my groin and i have basketball tryouts today. is it safe for me to tryout? its on my right side and its really close to the crease where my thigh meets my vagina

This : This is a general surgery question not orthopedics. You should consult a general surgeon to discuss the situation. It is not common for a female to have an inguinal hernia. The canal being smaller may put you at a higher risk of incarceration of the hernia. That would be an emergency situation.

Should be fine: Base your activity level on your discomfort level. You should be fine if it doesn't bother you. At some point however, you should see a general surgeon with experience in both open and laparoscopic hernia repair as we think that hernias are riskier to leave alone in women compared to men.

Yes: But you will need this fixed asap becuz if you are accepted to the team you will have a physical exam done and the hernia will be detected and surgery will be recommended.
