Hello there. I can understand your concern about your organ. But there is not much i could make out of your question. What kind of injury did you sustain? And where did it hit to be exact? And what knot like thing are you talking about? Better to consult a general surgeon in person for further evaluation and management. Your condition requires in depth evaluation to come to a conclusion and also a proper and clear history. Best regards. Dr. Anil kumar jain.
