Finishing up bad winter illness (on antibiotics) and think excessive coughing has caused reoccurrence of bad hemorrhoids for 3 days. (Have not had since postpartum.) Just noticed both groin lymph nodes suddenly sore and swollen. Connected?

Coughing/hemorrhoids. Intense and prolonged coughing may create recurrence of hemorrhoids, but having swollen groin lymph nodes is not a usual consequence. If you are unsure of the cause of the rectal/anal pain, it may be herpes virus , not hemorrhoids causing the lymph node soreness. See your gyn provider for an exam and testing to find out.
