Sort of funny story: I began walking up and down the street the first week. I got cocky and thought I could handle more than I could and decided to go all the way around the block.
Well, I had my bumblebee suit on (back brace resembles a bumblebee suit) and my cane and had a little meds in me though not much. I wanted to make sure I could walk. Well, I got just about exactly halfway which makes it the middle of the next block when the spasms and pain kicked in. I realized I had left my phone at home so I couldn't call for help, I was about to call a cab! I just put one foot in front of the other staring straight ahead until I finally was back in my bed.....in agony. I walk still but I'm actually still afraid to walk that far alone though it should be a piece of cake now. I still have fits of pain sometimes. I walk laps on my own block now so if something happens and I'm found face down in the sidewalk my neighbors know which house to drag my carcass back to. They actually watch out for me when they see me and cheer me on now.
Yup, baby steps and I'm always pushing it. I need to realize that 3 mos out isn't all that long.
Congrats on the successful surgery and welcome back. It sounds like you are doing very well. Unfortunately, pain (and sometimes lots of it) is a normal part of spinal surgery. Everything is "baby steps" for you. You need to walk as this helps to strengthen your back muscles. No one expects you to walk 5 miles. You can do you distances in short segments (remember baby steps right?) several times daily. Keep up the good work.
