I had a large (20 mm) kidney stone removed by lithotripsy four months ago.  Two lithotripsy treatments were required (12 days apart) to break up the stone.  Since then, I have had sciatica symptoms in my right buttocks and leg (the stone was in my right kidney).  Could the lithotripsy be the cause of the sciatica symptoms?
No it is not due to lithptripsy.but age related changes are the causes of sciatica. . If it severely need surgery, if mild exercise s are help full.see those on youtube
