I have a prolapsed disc at L5 which is compressing the right side nerve causing excruciating pain down right leg with tingling and pins and needles. I had two steroid nerve block injections a few weeks ago but although the pain went and turned to mild discomfort, pain has now returned when I put weight on leg. I will be having a booster procedure very soon but if the pain comes back after that repeat lot of jabs into spine I may have to consider surgery on the disc - to free the trapped nerve. I have seen osteopaths and physiotherapists but is there any stretching exercise (or anything) I can do to free the nerve that is being compressed? Fed up taking painkillers and tens machine makes little impact.
