U know when u have one. They\'re painful. When I got mine I had swelling for a week in my groin. I thought nothing of it because there was no pain and everything was working normally. Then when I was at work I felt a tingling sensation then s@#t loads of pain.
It was like I was stabbed in my groin for a split second... After that I felt a soft lump. I could push it back in, a few seconds later it\'ll just pop out again. A test to do is to put pressure on it with your figure then cough. If u feel it push out. It’s a hernia. That’s for groin ones anyway. Don\'t know about stomach ones.
