There can be a lot of reasons for groin pain, including sciatica, but that is more typically felt in the buttocks and down the leg. Groin pain can also be a sign of muscle or ligament strain, an indication of a bad hip joint.
Here is a list of possible causes and potential treatments form Cleveland Clinic:

Have you seen a doctor about this issue? If it came on suddenly, it can be a sign of injury, more gradual onset can indicate a wear disorder or inflammatory condition.
