My dad is a nurse and is 60 years old. He has been having severe lower back pain, where he has sharp pains shooting down his hips and leg. his legs and feet have started going numb. He had mri and was told herniated disc and bulging disks. One doctor said no severe arthritis, pain dr said that he thought it was something else and sent him to dr in durham. he wanted a stand up mri and insurance wont approve another one. what do u do? any suggestions? Having to work on his feet, thinking of doing disability but I hate for him to give up. any suggestions of how to deal with insurance and doctor.
