Hello,
Thanks for using Healthcaremagic!
I have gone through your query and I can understand your concerns.
Enlarged inguinal
lymph nodes are generally inflammatory in origin,usually due to infection around nearby area like your legs or groin.You might have small abarasion or infection around your anal area as per your history,it might be the source of the infection causing swollen lymph node.
As a first line management you can do the following.
1.Start a short course of antibiotics preferably "ampiclox" for five to seven days
2.Analgesics like "ibuprofen" or "diclofenac" for pain.
3.You can apply topical antibiotics in case of small wounds.
4.Hot compresses over the affected area provide symptomatic relief.
If symptoms persist despite the treatment, you might need detailed evaluation to rule out other causes.
Consult a general practitioner in case of resistant cases and you may require a
biopsy to rule out some other conditions .
Hope this information helpful to you.
Wishing you good health.
Regards.
Dr.Shinas Hussain
