Lymph node in groin won't go away
Hey there everyone so a month ago today I was showering when I noticed a large painful lump in my groin, I discovered it was my lymph node and the next day I had what felt like the flu(turned out to be some virus) I went to the doctor and he said not to worry about the node. I got better and the node started to decrease its been 3 weeks since I got better and the node is now painless and just a small lump. I'm worried though why won't it go away. I won't lie I have been poking at it constantly out of concern. Any help though?
