...hi, sorry to intrude... but I went through searches for years to find out what was causing my eyes to be red and sore; and now I am trying to find out about "stringy mucus" from one side of nose.... it can be surprising what we end up finding out.... my eye issue at that time (I now have unrelated Glaucoma) it was the office xerox machine toner! Recently I read about paper tissues we use to keep blowing our noses etc, can have a lot of chemicals in them and people are actually having reactions to blowing or wiping their noses with the paper - so they are suggesting fabric handkerchiefs which is a bit of a nuisance but who would think paper Kleenex would cause reactions in some users? Just thought would mention it; also stuffing in bed pillows... probably not a cause for you but have read some of the fabrics/stuffing is so processed its even worse for some people than feathers etc. Best of luck with your problem, I have similar issues plus a laundry list of other medical problems and it sure can affect our quality of life.
