Medical guides and websites out there will give you the symptoms of having a hernia. While there is a wealth of information out there, using guidelines from a reputable source such as the National Institute of Health's website may save you some time and confusion. The bottom line is see a doctor if you have any of them (bulge in your groin, feeling of tightness or burning in same area).
It is possible that a hernia can be misdiagnosed for a groin strain. To save yourself time, see a general surgeon who specializes in hernias.
Remember: when it comes to your health (and that of your family & friends) it is absolutely critical to be the biggest advocate for yourself and seek the right medical care.
