alipata, unfortunately there is no cure (yet) for autoimmune diseases like ours. The best we can hope for is to gain remission through treatment with medication, or more likely manage the symptoms and disease progression so that you'll life a pretty normal life.
I've had arthritis from age 5 and am now 50. I've done all the normal things - went to college, got married, had kids, hold a job, etc. It's not always easy, but you'll be okay. Hang in there!
There are over 100 different types of arthritis and migratory is a symptom of some of them. Migratory means that the arthritis is not just in one joint but continually moves around your body. I'm dealing with Lupus and it has migratory arthritis with it.
