Yes it really does wear you down. I'm finding myself getting agitated and snappy just doing basic things and basic conversations because the background pain just makes everything seem worse.

I hope there's an eventual end in sight for you, at least with sciatica its meant to eventually get better, though it's hard to imagine that at times.

I think it's worse when the pain isn't tied to a physical thing like a muscle or broken bone or whatever and its just this insidious non specific nerve pain that's always there. Really draining.
