Hello Kristy and welcome to the forum..
I am 63 years old and I had the Nissen 2 years ago this coming April. I have an office job also. I sit down the biggest part of the time. I was off work for a total of 18 days (weekends included). I went back and I was uncomfortable (around the waist, even elastic waist pants bothered the incisions) but I was not in pain. after the first week back I felt much better. My co-workers were great.. they helped me so that I didn't have to bend stoop or lift anything. I am blessed that I have the job I do.
Please let your body tell you when it is ready to go back to work. Mine told me to go for it and I did.. maybe 1/2 days would have been better the first week back, but I made it.. I work 8 hour days and I could not have come back any sooner than I did.
I do need to tell you that I would do this all again if necessary. It has given me my life back. And I have never been more blessed than I was the day I found this forum and made such wonderful friends..
Still looking for rainbows
