No, you've got that backwards, Purplegirl. IgM is produced first - it's evidence of a recent infection.
IgG is a response that happens later on in the infection.
This doesn't make your scenario wrong though. As the infection stays in your body longer, it "digs" a little deeper into the tissues and joints, making it harder for the body to respond to. So it can be more difficult to get an IgG response for some.

I break up my post because my eyes have been effected by TBI's as well, making long paragraphs very hard to read.
