can anyone advice what I can do to improve my sitting time. I eventually had disc decompression 6 weeks ago following long period of sciatica, my surgeon found 2 large pieces of disc broken away and also had to free up the sciatic nerve canal. I am doing very well with my walking up to 3 miles now and have done 4, my flexibility on standing is good, however since week 3 I have not been able to sit down. I am off my pain medication although I have a dull ache in the lower back I can manage that, unless I sit down I. When I try to sit I can feel it tightening after 7-8 minutes and cannot bear it after 10 minutes which forces me to stand up. Straightening and standing from sitting causes a sudden severe pain in my right side which then forces me to lie down flat with my knees bent. I have had a an MRI and am awaiting the result. Will it show muscle atrophey ? I think I need Physio to stop this but they are nervous of doing anything until I can see my consultant which is later this week. I want to go back to work but I can't even sit to eat a meal. How long will this last ? What can I do to help myself? Has this happened to others? Will the MRI show me the answers ?
