Thanks so much for your reply, Grace and Alli.
I've had no other symptoms besides a sore throat and swollen lymph nodes just on the right side of my neck, no sign of blisters. Today the pain has eased a little when I swallow, thankfully.
When I look down my throat I don't see any spots, etc, which is what led me to thinking it might be something else. I guess where my anxiety rose from was the fact that these symptoms appeared 1 week after I had sexual contact, and one of the first things that popped up when you type in swollen lymph nodes, is the possibly of HSV. I wasn't sure if that on its own was a sign of HSV, or if those symptoms had to be accompanied by the traditional symptoms, such as blsiters, etc.
Thank you for your thoughtful response, it is very much appreciated. 🙂
