If your own Physician told you after having tests' done and medication given to you it just doesn't sound right that now a Neurologist is saying "NO". With even having your Physician baffled. I'm not saying to find another Neurologist however I would definetly have another MRI done, a spinal tap, everything that is required to determine whether it is MS. Could the Avonex Inj. helped with what your Physician said was MS. It is hardly likely that when your told "yes" MS and then "no" This disease does' not just disappear. You are still having symptoms that are unexplained then. I know myself that I had an MRI done and the Technician read the report wrong and the MRI had to be redone. Could this be a possibility. I myself am at a point of getting tested due to the unexplained pain I am in, now your making me wonder. Just as I have 2 pinched nerves in my back and 3 vertabrae that have joined, yet the last Back Specialist I seen took an x-ray, not an MRI and told me that there was nothing wrong with my back and if I didnt like what he had to say to bad. Prior to, my Physician was having me go to another Back Specialist who told me I needed surgery. I often wonder myself, are these people out to help you or just make you feel less of a person. You know yourself the pain your in, your previous diagnosis. Look for another Neurologist, your Physician may not like it but you are the one suffering not he/she. Type in Neurologists' in your area and see what kind of comments are left from others'. I believe you type in Physicans Ratings and when you find one that has a 4 or 5 star tell your Physician you would like to see that Neurologist. I wish you luck and a much better explanation as to what is causing you the pain your in if it isn't MS, then what is it??
