I had L4 L5 prodisc total disc replacement...for approx 6 months and light physio i felt a bit better...but then started more intense physiotherapy and graduated back to work....now i have a numb left foot with likely nerve damage..it is numb but it still hurts and i have shock like feelings in it if i lightly touch my ankle area...eg while shaving my legs!!!!! now i have stopped working again...until furtheri investigation....i beleive a physiotherapist did this to my back while performing a chiropractor like movement on me....but realy no way of knowing for sure....my lumbar area is also aggravated and in intense pain most of the time now as well....has anyone experienced this so long after surgery??? its been a whole year!!!! thanks
