<human>: My 28 year old son had one lymph node removed from his groin area over a week ago (along with a large cyst near his spine that had become infected). My question: The area at his groin seems rather swollen and hard. It is not red however and he has slight pain. Is this normal or is there a need for concern. He resists going to the ER and the surgeon is unavailable until Wed.?
<bot>: Thanks for asking in Chat Doctor forum In short: I think removal of lymph node is for biopsy? Explanation: Usually lymph node is not removed only for infection. Maybe they have taken it for biopsy and study. So, another swollen and hard area may be another lymph node or may be because of inflammation of surgery over there.  So, there is no pain or any other symptoms you can wait till the report comes or else visit a doctor without hesitation.
