Hi to all,i have a shed in my garden which i had built last year but unfortunately each time i occupy it my ears start to swell and feel full.I had ears examined and they're ok but have been down almost every avenue to cure this problem but still no joy,is it an allergy type thing, or a chemical reaction to something, i really cant nail it.

Ive not been in the roomspace for a while now as the effect can last for a week or two so i've gave my ears a break.Have developed tinnitus in my right ear as a result of this which is very high pitch and worse when there's silence.

has anyone come across anything like this before,?it only happens in the building and knowhere else.
