Avrom, My dad was recently diagnosed at age 74, but had been showing symptoms for a long time before that. He has suffered from chronic muscular aches and stiffness for most of his adult life. He also has allergies and chemical sensitivies, which have worsened in recent years. He has been complaining of headaches and balance/nausea problems since Christmas, and the fingers of his left hand are very stiff. I too have chronic muscle pain and stiff hard muscles, especially in the forearm and calf. I also have serious allergies and asthma, vestibular problems and have had a couple of bad cases of vertigo. It isn't clear to me that these symptoms need to occur together, and it may be coincidental that you have them in your family too. Certainly, I have learned the hard way that the autoimmune problems associated with allergies can cause a very diverse set of symptoms, including muscle spasms and headaches, which I have had since childhood. But it would be interesting if there is a genetic pattern here that links these disorders with parkinsonism, wouldn't it? By the way, there is also ADHD (hyperactivity) in his family. Shelley
