So I have a question. What should I look for to check for a hernia. This morning I noticed a small bump (hard consistency, pea size) right where my groin meets my leg. I have done some research and have checked for pain, being able to push the bump in (it won't), and tensing the abs to see of there is a change in the thing. My guess is that it is a lymph node. Any other things I should look for to rule out a hernia?
