Hello, this morning I woke up and noticed that the right side of my pelvis was somewhat tender to touch. So I felt around and felt a small bump under the skin where the leg meets the pelvis on the right side of the pelvis. I am assuming that it is a lymph node. I am curious if I need to worry about HIV causing this. A little over 3 months ago I open mouth kissed, fingered, and received oral sex from a girl that I thought was clean but have heard after the fact is promiscuous. Also, I was out of town recently and woke up yesterday morning with what are without a doubt bug bites on the right side of my buttocks. Probably bed bugs. Would the bites most likely be the cause as I noticed the swollen nodes the day after the bites? Or should I be more worried about the previous situation? Thank you for any insight!
