I work in an office too. I had my op on the 9th and went back on the 19th, so 10 days. I am still having the odd bit of discomfort but ten days was perfect for me to go back to work any longer i would of felt like i was wasting my annual leave. I just strongly advise to rest rest rest for that time that you can and have someone there to help you, i really underestimated the pain but luckily still live at home so they were there to help.
As for driving though I only work 5 minutes from my house and i struggled even doing that. I would say now im just over 2 weeks post op I could drive for a bit longer and have more strength and stuff! you dont want to push yourself so the automatic would be a lot better if you could do that! good luck!!xxxx
