<s>[INST] I got dog biten on Oct 3rd,the punture wounds healed nicely but there is a huge hard knot there..Went to ER twice gave me antobotics both times and said the last round of antibotics should make the know go away and it hasn't.Do you know what may be going on? [/INST] Hello,Welcome to HCM, The symptoms of knot after being bitten by the dog, as it was a lacerated wound which had lead to loss of tissue due to which it has healed by leaving that scar.Even after taking two courses of antibiotics the knot suggest that the wound should be healed completely.I would suggest you to apply hot fermentation over the wound and also you have to take serratipeptidase for rapid reabsorbtion. Thank you. </s>
