I read through your query.
Oral herpes normally presents with very painful cold sores, and the patient subsequently develops fever and muscle aches. There can be some tender lymph nodes in the neck too. The issue is, it is highly contagious and can be spread through kissing, or through infected saliva, and even close contact. So right now, you should avoid any acts of kissing.
As i told you before, if it's possible better get examined by a local doctor to confirm its herpes. Once its confirmed normally we ask the patient to use tylenol for fever and muscle aches, drink plenty of fluids, and specifically for herpes we advise Famciclovir Tablets 500 mg every 8 hours for 7 days. People who complete the regimen don't normally get infected the second time without exposure, and have lesser recurrences.
Please get examined by a local doctor, so that he can confirm, and start you earliest on the meds.
