Swelling and pain. In general, lopsided groin swelling and pain with activity (especially lifting, staining, and coughing) are highly suggestive of a hernia. You can have it on both sides too. If your bowel is caught within the hernia, additional symptoms may include nausea, bloating or problem with bm. If in doubt, please check in with your doctor.
Bulge. It can be a bulge with or without pain.
