I had four removed under a GA approximately 12 years ago. I remember waking up in recovery and noticing that only 35 mins had elapsed since I was wheeled in until I woke up (sort of).
Back in my room the pain started to get quite bad after 2-3 hours and I asked the nurse for some panadeine forte. She told me the surgeon had said I could have panadeine clear (the weaker version that dissolve in water). Initially I was disappointed however they worked very well and took away 90% of any pain I experienced.
I was off work for 2-3 days from memory.
Personally, I would recommend a general anaesthetic rather than a local one.
Good luck.
