Hi maison
I understand you must be very eager for cll. I probably can't say it is impossible to go back to work in 3 weeks but it is pretty much close to impossible. You need to know this is a really serious stuff. I know SLM got back to work soon but he also regretted it and does not recommend it to anyone. I think SLM is just an exceptional case and DO NOT expect you are an exception. Everybody is more or less similar.
1. Even with a full weight bearing like Stryde, you can't walk anywhere close to normal walking. Walking is also getting worse and worse as you lengthen more and more. In fact, 4-8 weeks are the best moment for CLL, since you recover from the surgery and haven't lengthened that much. Trust me it will get worse and worse down the road. (if your goal is 5 cm or so, it may be fine.)
2. You will have constant pain all the time just at different levels every moment. I had quite serious pain (it is very subjective.) so I couldn't really do much activity or sleep well. I slept only 2-4 h in total everyday and woke up 3-4 times or more. Everyday, I was exhausted.
3. You also need to do lots of PT to be able to lengthen enough and recover better, which takes time and burns your energy. At work, you can't do PT and you may be in trouble at late stage of lengthening. Or your late stage may come so early like 3-4 cm.
4. You can't sit down in any chair for a long time. This long time means not even 30 min. Sitting is also quite uncomfortable so you can't sit in any comfy chair for a long time. You are also supposed to stretch your legs in high position while sitting.
5. Working in general is pretty serious thing. Obviously you can't perform anywhere close to 100%. At best 50% perhaps not. If your position is not high, your job will be at risk. Your coworkers will be also unhappy to work with you.
6. You will have a super high risk of getting your secret of CLL to be revealed. Personally, this is the worst thing and I care about my privacy the most. It is up to you to take this risk. Or if you mind, that is ok.
I went back to work 5 months po. It was still though. You said you changed your mind from 3 weeks to 4 weeks. This doesn't make any difference. It is really up to you. This is my last post for you anyway.
