My partner has suffered with lower back pain for many years, however since having treatment for kidney stones two years ago, the pain has become worse. He is on pain relief tablets every 4 hours, and has been everyday for the last two years! Whats going on, he has been told he also has a nodule of some sort on his lumber spine. One other thing when he was a child he was kicked in the back (kidney area) and had been in hospital due to passing blood in his urine after this incident. I believe there maybe inflammation in this area that is being continually reinflammed due to regular movement. Has anyone experienced anything similar, or could offer advise on what might be going on? He is becoming more and more immobile as the months go by?
