Im having groin pain and cant even walk. could it be hernia? or just muscle tear? i play soccer. and did the splits by accident.

Possibly: It is possible you have a hernia, but another possibility that seems more likely is that you have injured your hip; especially with the info provided that you can t walk on it and it may have begun after "doing the splits by accident". Hip problems often cause a referred pain that goes to the groin. Don't hesitate to be seen for a specific diagnosis.
