I've had dry mouth for most of my illness. I suppose most people would point the finger at the prescription medication I'm taking, but I'm wondering if it could be something else like sjogren's syndrome. I just got tested for Lyme and it came back negative although I don't want to completely rule it out since testing can be inaccurate. The doctor also thinks I might have bartonella because of my other symptoms. I do wonder about sjogren's syndrome. I'm guessing it's very rare, but it would still be nice to rule that out.
