swollen lympnodes

I had the protected sex with sexworker but i don't know that my condome slipt or not ( i was drunk).
after five weeks i have swollen lympnode in the right side of the groin . I am worried since o never had
swollen lympnode in never had swollen lympnode in the groin before . lympnode is swollen even after 16 week .
and is slightly  painful ,there is felling of discomfort in the groin . I keep on touching it
three or four times of the day .
Is it some of the STD or do I have HIV?

If you are worried you can test.
And swollen lymph nodes are a sign of many things but not an STD. And most people can't not find lymph nodes and if they do, do not know that they are swollen because they don't know what it normally feels like.
