I'm pretty sure I had mono but, I need to be sure. For about a few months, I had a sore throat and the lymph nodes only on my neck were swollen. Now, my sore throat has completely gone away and my lymph nodes have shrunk back to normal. I just want to make sure it wasn't hiv. With that, I heard all of your lymph nodes are swollen and don't go away. Mine have gone away. Am I fine?
