Achy lymph ndoes

Good morning all, 

I just wondered if anyone had experienced anything similar but for 8 months now I have had slightly swollen lymph nodes in the right side of my groin that don't particularly hurt but they do ache at times. 
 

I don't really have any other symptoms and the lymph nodes have not got any bigger they just stayed the same slightly hard but moveable.

 

i went to the doctors previously they had a quick feel and said it was nothing to worry about but I'm really scared it is. 
 

Has anyone gone through anything similar?
