Thanks for your answers. If it is an allergy to something round the home I am baffled. We have no pets. I use a synthetic covered pillow. Our bedding is washed frequently. The only likely culprits are the carpets, which are hoovered regularly, the central heating atmosphere, the biological soap powder which has now been changed, soaps and lastly the goose down quilt which we have had for a number of years.
I suppose one remedy to test them would be to change address for a period.
