I doubt you acquired oral herpes from that exposure. It is much more likely that you caught a garden-variety cold virus, you could have acquired during the kiss you describe, or from someone else. That infection caused the "sinus" symptoms and also triggered an episode of oral herpes that actually existed previously. (Oral herpes often is triggered by an upper respiratory viral infection. That's why they're called cold sores, after all.)
HSV simply cannot cause symptoms within hours ("later that evening"); it takes at least 2-3 days and often up to 2 weeks. When initial oral herpes causes symptoms, generally there are multiple lesions inside the mouth, not a single sore outside the mouth, such as "around the lip". "Sinus drainage" would be an unusual herpes symptom.
Most likely you have had oral HSV-1 for years, probably acquired in childhood. If your doctor had done a blood test for HSV-1 when you first presented, and if it was negative, and if a later test became positive, that would prove recent acquisition. But a blood test done now probably will be positive, in which case you'll never know when you acquired it. (On the other hand, it is possible that a blood test would be negative for HSV-1, which would mean that none of your symptos was due to herpes. So it still might be a good idea, although it's optional.)
Regardless of when you got it, herpes is not causing your continuing lip burning, headache, ringing in ears, or pain/tingling in your butt; HSV never causes symptoms like those. You should check back with your doctor if they persist.
