Hi, As you had lumbar lecithesis at L4-5 level post trauma during physiotherapy so if the injury is stable which can be decided upon MRI Finding & clinical examination it can be managed conservatively by 1) Avoiding bending forward 2) regular physiotherapy 3) warm compression 4) Vitamins (methylcobalamine, folic acid etc ) 5) analgesic , proton pump inhibitor , muscle relaxant as and when required 6) LS Corset belt if required Otherwise if unstable then operative fixation may require . So in my opinion Visit an orthopaedic surgeon preferably spine centre for further management and opinion ( If you have stable injury and can perform the job if spinal mobility can be imobilised during working hours ). Hope this will help. For any queries feel free to ask THANKS N REGARDS
