I went to a laundromat and found myself itchy suddenly when I opened a washer to deposit my clothes. So I took everything out and used a machine in the back. I eventually dried half the clothes and took home half undried. I hung out the wet clothes at home and started feeling itching again. Also my throat/chest felt unusual. Over the next few days I felt breathing was labored.
I put some of the wet clothes upstairs and eventually re-washed the whole thing. But the "stuff" from the clothes seemed to be in the house and when I opened the window for hours to clear the air - it spread it all over the house. Now my mother clears her throat often and I feel discomfort in my chest. What could be so persistent (over 6 weeks now) and is it dangerous? I just had an x-ray and breathing test-all was ok for now. Any ideas - would appreciate any useful insights or info.

Thanks.
