Had my dyneses operation in March 2007,had NO physio,but all seemed to be ok. BUT!!!! its all going pear shaped,after sitting down for only a minute i cant straighten up. Lots of pain down my left leg and numbness. Made my mind up im having it taken out,as i dont trust the procedure. Screws are becoming loose and nerve damage is taking effect. 1 word of advice DO NOT HAVE DYNESES!!!!! My research has been intensive.
