My friend had a second back surgery the second surgery was for a herniated disk, now almost three months after surgery he is in chronic pain has numbness in the groin and anal regions, his leg twitches and has a mind of its own he cant sit and is limited on how much he can stand for fear of falling.  He has now been on morphine for about two months thats how much pain hes in is that normal for this type of surgery?
First I would like to know what was patient complaints before surgery. Are these new symptoms after surgery? Does he have any bladder issues? Due to severe disc herniation one may present with severe leg pain and numbness and weakness and such patients gradually recover after discectomy. However, if this is new after surgery this needs to be investigated and It's normal to have such numbness and so much pain. Thanks.
