This sound very distressing. Further to my earlier comment, see what your doctor thinks about having O2 at home for a spell. It sounds a bit defeatist when you are young and active, but may only be needed for a while. Agin, deep down air. Bugs do not like it.
You have taken steps to reduce allergies I take it? Vac-ing the bed with a (Heppa Spelling?) Filtered cleaner, and keeping your distance from pets for a while etc. etc..
