Hi. I recently got treated for chlamydia and I don't have it any more. Before that issue I had a single bump on my pens and my doctor said it was just skin irritation. After the chlamydia incident I got tested for everything else syphilis herpes hiv gonorrhea etc and all came back negative. I have this rashes on my butt and I'm scared because it says herpes can do that but I had them while I took the blood test and it came back negative. Could this just be eczema cuz it has been dry and I had three different doctors look my genitals even the bump and they all said it's not std related. Just looks like a normal rashes and yes they are stabbed over from me scratching but there's no oozing or anything like that I'm just scared because after the chlamydia I'm paranoid.
