What Is The Cause For Chalkiness On My Fingers With Increased Stomach Problems?

For about two weeks now I've had a chalky, dry feeling in mouth, nose, and a sense of chalkiness on my fingers and around my eyes, as well as increased stomach problems. I know there are medical conditions that have these symptoms and that some medications can cause them, too. I am not, however, pregnant or on any new medications. However, the landlord sent some people to repaint one of our hallways around two weeks ago, which they did after first sanding away the previous paint. They and we cleaned up most of the areas they were working in, but there are some big areas that are just too high up to wipe down. Could it be possible that I've been foolishly inhaling residual paint dust all this time - and how much in danger am I in now after two weeks of doing so?
