I have been suffering from many of the same symptoms as some of you: Joint pain, muscle stiffness, swelling of lymph nodes, headaches, nausea, feelings of fibromyalgia.
I found out about a disease that is found only among Japanese children under the age of 5 that suffer from these same symptoms. It has only been known about for the last fifty years. I even went as far as to look back into my heritage to see if there is anyone of Asian descent because it sounded so much like what I have. There wasn't. I have been drawn back to this website over and over because it sounds so much like what I have been experiencing. I went there this morning and they have found out that now it is starting to found among adults of other ethnicities. It is called Kawaski's Syndrome. When you read the article make sure you read the entire case study about the adult and when you go back to the doctor print the article and take it with you so that you are not quickly dismissed due to the fact that not many doctors know that it is also found other races and ages. This is a great discovery for lots of people who are suffering. Please let me know how it turns out for all of you. I hope we can all get some answers now.
