Freaking out

Kr

I have a strange textured patch on my lip that is itchy and feels numb like and also multiple itchy patches on my face. I recently got hydrated copper sulfate spray on my face so I thought it might be eczema but I’m now pretty convinced that it is herpes and I am freaking out. I will call the dr on Monday but have any of you ladies used an at home STI test kit ? Like the kind you mail back? I am considering it because it is extremely difficult to get my drs to order a blood test that I can make it to. Most of the drawing centers are pretty far from me and I am really worried 😟
