question: My husband is having severe pain in his back - both lower back as well as specifically up on the right side between his angel bone and spine. His legs are also very painful and tingling. He is a relatively recent kidney transplant patient but has been doing very well in terms of his kidney function numbers and post-transplant biopsies. He exercised (elliptical) Monday night and that seemed to aggravate the symptoms. The pain has been very severe today, He can t sleep, has tried some pain and sleep medications to no avail...
