Hi Gijuie, and welcome to the board!
There are lots of us fusion folks here, and we're happy to try to help you from our own experiences. It's a big surgery, and it sounRAB like you realize that. Doctors aren't always quite up front about how long the recovery period is. You're right, you'll need about 3 months off work. Some go back sooner, some later than that, but 3 months is about average.
There's a sticky at the top of the page called, "Post Surgery Tips." It has tons of great suggestions that will make your recovery easier. My best tips: get a satiny type bottom sheet for your bed. I got slippery pj's, too, and together they made turning a breeze, so much less painful than the friction of cotton on cotton. You can slide to turn instead of having to shift your weight. For the same reason, put a plastic garbage bag on the passenger seat of your car for the ride home from the hospital. You can slide to get in and out. Put a big ziplock bag in there, too, in case you get nauseous. You can zip in the mess and no one will have to clean anything up. Also, get a ood quality grabber tool. It will be worth its weight in gold your first day home. You won't be able to pick up anything that you drop without it, and it will also enable you to reach things that are just a little out of reach without having to move. That makes a big difference when you're in pain. Get a little notebook to keep track of your meRAB. You'll be groggy, and it's easy to lose track of how much you took and when. Every time you take anything, jot down the time, which med, and how much. I also kept a running list of questions for my doctor in the same little notebook.
There are a ton of other great tips on that thread. If you have other questions, we'll do our best to help. I've had two fusions and don't regret either one for a second. I'm not pain-free, but I'm much better off!
I'm sure others will chime in as well. You're officially a meraber of the back buddies club now!
Blessings,
Emily
