I know it is. Please go and get them swabbed. Make sure the Dr does a type specific test so if it is hsv you will know if its hsv1 or hsv2.
Do not let them just look and say oh it's herpes. Demand a culture.
Get into a Dr asap and good luck
Please keep me posted
Herpes lesions do not go away in two days. It takes ten days mminimum. Your boyfriend having a cold and an ingrown hair has nothing to do with hsv. Hsv initial outbreaks very often have flu like symptoms after sores appear. These symptoms include fever, body aches and swollen lymph nodes.
What you describe really doesn't sound like a herpes outbreak. Especially not the primary outbreak.
