Enlarged lymph nodes

Afternoon all, I'm on antibiotics for what the doctors have called reactive lymph nodes that I discovered on my neck. Just today however, I have also found 2 swollen lymph nodes in my groin area which caught me off gaurd. Having both enlarged lymph node in the neck and my groin, could this be a sign of something worse than reactive lymph nodes? I feel well and not sick. 

 

Thanks (I've reposted this to a different topic as it is the weekend)
