Hello and welcome to ask a doctor service. I reviewed your query and here is my answer. Are you sexually active? How many sexual partners do you have? Is any of them suffering from some disease? Is there any discharge from your genitalia? Do you run fever? Do your joints hurt? The lymph node in the groin area is suggestive of infection in your case as you said you have cough, sore throat and eye infection. But it looks like you have got sexually transmitted disease. You will need to run some test to know exactly what it is. Hope i answered your question. Feel free to ask more if you need further assistance. Thanks.
