I had three taken off, 20 yrs ago.
Agree on the pain of the LA down the side of each toe - apparently, it hurts because the flesh there is really tight, so the anaesthetic has to be forced in (that's what the doc told me, anyway).
After that, a big rubber band around each toe (to curb the bleeding), and a good bodging under each nail with what I recall looked like a cocktail stick covered in pink goo.
Nails ripped out, rubber bands off (cue loads of blood), dressings on, then sorted, all by about 4.30pm.
I remember looking down at my feet about midnight (clad in the softest shoes I could find - pale tan), in a local late-night hostelry, and seeing blood stains coming through! So I got another beer
Worst bit was the injections, but if I'd known how good the relief was, I'd have had them done 5 years earlier.
