Y'all ever have this??

So, last night I was laying on the couch while my husband was in the bathroom and I felt an uncomfortable feeling on my upper thigh around my bakini line. I started feeling around, and I felt a lump right on my bakini line closer to my butt. It's about the size of a bean, and it's not really painful. It's more or less very uncomfortable when there is pressure being applied. It feels uncomfortable and slightly irrated in the 2 inch radius around it on my thigh area. Looking directly at it, you can't tell it's there. No bruising, no marks. You have to actually feel and apply pressure to know it's there. Should I be concerned or worried?? Have tall had anything like this before? Could it be a swollen gland or lymph node or something?
