I had it done, left toe on NHS in 1979, right toe in Australia in 1982, CET Junior has just had his done this week on NHS, his week wasn't as long, but it does mean waiting rooms for hell for the several times he will need to dressing changed until its fully healed. I had a similar experience with podiatrists trying various techniques to trim bits back, which were about as effective as King Canute holding back the tide.
I've not had any problems, although the Aussies didn't to a good job and the nail grew back not at full strength which has left it susceptible to nail fungus.
Took up running again aged 47 and managed half marathon distance 70 times on them, so no long term issues even with the nail that grew back.
Mini AO will be up and running soon.
