I was fine while in hospital for the overnight stay, later in the day after released at home started to have a low grade fever. This fever got to 101 and ranged from 99-101 for about 5 days post-op. The first day I had the fever I called doctor immediately and he phoned in a perscription of Augmentin which is a very good antibiotic for those hard to kill infections normally seen in a hospital. I am totally fine now with no problems what so ever. I am now 3 weeks post-op and have lost 31 pounds and back to work and working out. Hope all works out, but the main thing is to get out of bed and start walking around as soon as possible and make sure that you did the breathing execises to clear the lungs out, that can be a cause of low grade fevers as well.
