It does spread and at it's own pace. It's different with everyone. It will go from arm to foot, arm to arm, internally, in the back, you name it.

It does effect the immune system also. I get a flu shot and a Pneumonia shot to help fight off getting anything. So far so good. Both my Grandson's have been sick and my kids but so far I haven't gotten it. The Pneumonia shot is given every 5 years.

Have you had any blocks? With it spreading, the blocks might be able to stop the spread and even put it into remission.
