I have painful swollen lymph nodes in groin. Please help?

Hello,

Welcome to icliniq.com.

First of all, please do not freak out. If we have adequate information, it would be easy to figure out the cause for such groin node enlargement. It would have been a little more informative if you could mention the size of the node that you could feel, whether on single or both sides? Whether it is a single node or multiple? If multiple, whether they could be felt discreetly or they are stuck together? Also, do you have any history of fever recently? That could have given some idea about the nature of these groin nodal swelling. The most common causes for the enlargement of the groin nodes is any infection or inflammation in the sites they drain the lymph fluid, which includes the genital area (including the lower third of vagina) and legs. So, I would like to know if there is any genital infection or ulcers, or any infection or wound in your legs. Many times, in sexually active individuals, it could represent a presentation of sexually transmitted infections like chancroids, syphilis, or sometimes in herpes too. Please get back to me with details so that appropriate cause can be identified and treated appropriately.
