My dad was in a car accident 3 months ago. has a broken femur with a rod inserted and connected at the hip and knee. he has just recently had a lump in the groin area that is very painful and had to go back to using his initial crutch with four legs he was using a cane.
Hi. Thanks for your query and an elucidated history. This looks to be inflamed lymph node as per your history and site. Just get confirmed that this is not an obstructed hernia as the site will be same. If a node, a course of antibiotic and anti-inflammatory medicines would solve the problem. If required ultrasonography and FNAC helps for a better diagnosis under the care of a Doctor.
