My 35 Year Old Son Was Very Sick 2 Weeks

there are various potential causes - please read the full answer
Detailed Answer:
Hello,
swollen lymph nodes can be caused by a variety of disorders. The most common ones are benign.
Although hematologic malignancies are possible as well, it would be unusual for them to present with isolated inguinal lymph node enlargement (and tenderness). Sexually transmitted diseases, leg injuries or infections and sometimes hematologic malignancies or autoimmune disorders may be associated with inguinal node enlargement.
In such cases, when the cause is not readily evident, we have to search for enlarged nodes in other parts of the body like the neck, armpits, etc and also for enlarged internal organs (spleen, liver). A chest X-ray or (better) a CT scan of the chest may reveal enlarged mediastinal lymph nodes and an abdominal CT scan may reveal abdominal node enlargement. If the radiological tests fail to identify the cause, a lymph node might have to be histologically examined (biopsy).
In your son's case, since he had an acute disorder, the most likely cause is an infectious one. If his symptoms improve, the nodes get smaller and less tender and the lab tests are not suggestive (or suspicious) of hematologic malignancy then he can be followed up with ultrasound scans of the enlarged nodes. If the nodes keep growing then an exhaustive investigation should be carried out.
Obviously, I can't say what the cause is but I have suggested the best course of action - according to my opinion.
I hope I've answered your question. Please let me know if you need further assistance.
