24 year old male. No sig. Med. History. Last November I found a hard node in my right inguinal canal just lateral to my scrotum. Went in for a pelvic limited US, report came back with no testicular lesions, but a calcified focus in the R inguinal canal with posterior shadowing. 6x3mm. They suggested no further follow up and declared it a remnant of infection. I don’t have any history of STI, and since then I’ve had other node problems. Should I be concerned about this node? What causes this?
