Dr Nelson is a very nice person and man. Dealing with Chronic Pain and severe back & beck pain, I always questioned the outcome. Basically it came down to his diagnosis being«It was all in my head», but would give me injections and prescriptions. Because of He and Dr Tien’s prejudice and«them being the experts»! I have permanent nerve damage in my arm and hand. I cannot open my hand all the way or use is for normal functions. If you want anything done right and an honest answer go to OHSU or Oregon Spine Care.
