I've recently injured my legs in a fall, and since then I have been able to notice swollen lymph nodes on each side of my groin. Beneath the left lymph node, another small lump can be felt. It isn't bean shaped like the lymph nodes, so I suspect this to be a hernia. Along with these, I have experienced slight abdominal pain throughout the day, more prevalent toward lunch time. To note, I am 16 years old. I'm hoping for some advice as to what I should do from here.
