Welcome to HCM.
Vaginal yeast infection could not be a reason for the inguinal swelling.
In early HIV, isolated inguinal swelling on left side is uncommon. Here in HIV, the lymph
nodes would be bilateral, multi-centric (more than three sites) and painless in nature.
STD lymph node enlargement is common. Other than in syphilis
, the lymph node enlargement will be associated with pain. In syphilis it would be bilateral, rubbery and painless.
Other than HIV/STD, tuberculosis
and non-infectious swelling of groin like inguinal hernia
also to be ruled out.
Consult your physician, he/she will examine you and with appropriate investigations will fix the diagnosis and guide you further for treatment.
