Has anyone had sphenopalantine nerve blocks? What did it feel like, did it help, would you recommend, were there side effects, etc?? Any information would be very helpful! Thanks!
Suggest you run a search on the term "sphenopalatine" at the top right of this page. You'll find four pages of past discussions of the topic.

The SPG block won't last very long, from a few hours to a few days. Since this is a sympathetic nerve, you shouldn't feel numb either (except for when you first get the block, you may feel numbness in your upper palette). It's more of a diagnostic aid than a pain reliever.
