Why is MS so extremely difficult to diagnose? I am the only one in the country so far on a federal medical disability retirement and SSDI for having 100% of the symptoms of Progressive-Relapsing MS, a classic text book case, without a diagnosis of MS or any illness or disease. The neurologists I have seen have done more then $100,000 of extensive and elaborate diagnostic and lab testing, the finest and best known today, for diagnosing any known illness or disease, but everything comes back normal. Every known neuromuscular disease, strokes, TIA's, and any known illness or disease ever discovered in the last 150 years has been ruled out, except MS. MS has not been ruled out or in. I have ringing of both ears and vertigo, without diagnosis, since tests come back normal. I have noticeable progressive neuropathy in the legs and feet, without diagnosis. Now I am home confined, largely bedridden, unable to drive, hourly relapses, monthly progression, loss of some sight and some hearing, loss of all reflexes, severe pain, loss of most swallowing, impaired breathing, and I am in an electric wheelchair, since everything begin overnight in October 2004, without diagnosis. That means I cannot be prescribed most medications or treatments, without a diagnosis. Steroids cleared up some of the hot and cold sensations but I cannot be on steroids for any length of time. I am currently not on any medications. But as a Christian, I remain very positive and I ask for no pity. It is a shame I cannot be diagnosed.
