Help please 😭

Hi everyone, I’m out of town currently and will be seeing my family doctor upon returning home for a test/swab regarding this. I have extreme anxiety right now and just wanted to see if anyone had any input or advice with this type of thing in the meantime

So I had a new partner about 5 days ago, we did not have penetrative sex just oral. We made out, I gave him a blowjob and he fingered me afterwards. I asked him and he said he was tested between his last partner and me, but I know things like HSV are not tested for in a routine STI exam. I didn’t think anything of it- so stupid I know- until last night, when I noticed the area was itchy (4 days after sexual encounter) I also noticed my throat was sore, but I drank some wellness tea last night and it does feel better since. A lymph node on one side of my neck is a little enlarged. I also travelled from mild weather to a cold place (this was 2 days after the oral), so I’m unsure if that is just my immune system trying to fight off a cold or if its HSV infection. The area isn’t painful or burning, no chills, or fever, no pressure in my abdomen or sores

A little backstory I have very fair sensitive skin, as you can see on the left hand side of the photo near my leg crease that’s 100% from shaving. Typically I use a clean razor with a gentle cleanser like cetaphil to shave that area, but I was in a rush and to just quickly trim some of the hair away I used a not new intuition razor (has shaving cream built in- these have given me razor bumps in the past). I was also sat on a plane for hours the day after I trimmed, and I wore 2 pairs of tight ish pants most of the day after so in my mind I’m thinking this could potentially be from sweating and irritation from my underwear? This photo was taken today, this would be day 5 since the sexual contact

Being irresponsible in that way all I can think of is that this is HSV, but some of the symptoms I’ve seen and read online do not align. I’m extremely anxious and freaking out at the moment, I feel something is wrong with my body but I can’t tell if I’m thinking too much or if this is cause for concern
