I want to caution people that Lyme disease can mimic ALS. I was misdiagnosed with ALS and am finding hundreds of others that were, that was really Lyme disease. The symptoms that set it apart from ALS are as follows: Night sweats, ringing in ears, horrible unrelenting joint and muscle pain, loss of hair. Blood tests for Lyme are notoriously unreliable. If you are having these symtoms, THEY ARE NOT SYMTOMS OF ALS! Carefully outline your symptoms for your doctor and seek a different doctor if that one ignores you.
