Hello,
Thank you for choosing DoctorSpring.
It does seem that you are having a Primary Herpes outbreak. I understand that your symptoms are severe, but do not worry it is nothing out of ordinary. In many individuals primary infection can be quite eventful. This does not mean that you are going for complication like Herpes encephalitis.
The yellow crusts does not mean virus or colonisation. They are just dried up mucus. Do not worry about that. Its part of body immune reaction - which is a good thing.
You should consider taking antivirals if the symptoms persisting. (even though it is bit later for anti virals) You can also take OTC pain medication like Ibuprofen 400mg twice daily.
In case of Any usual symptoms - weakness of arms /legs / unsteadiness / vomiting / altered consciousness - you should get in touch with your Doctor.
Hope this helps
Feel free to ask followups.
Thank you
