I think you are playing with fire if you think you can catch it in time to treat it. The symptoms aren't always that obvious, and I suspect that something that starts out mild (and maybe not so noticeable at first) could become much worse over time. Those ones I've heard of that spread to the eye - I don't think they started there.
It's not like I'm hearing of tons of side effects from the shot. That might be different.
And what about side effects from that early treatment?

Yes, that's it. I'm looking at "What's the least bad, bad outcome...?"
That anti viral drug, as I recall, had quite a benign toxicity profile, so it's got that going for it. And, I keep trying to find a Shingrix horror story and son of a gun, I can't really find any myself.
