I'm changing anti-allergic bedding every second day and vacuum the mattress & the whole apartment every single day. You can't imagine how annoying that is. I even purchased a very expensive air purifier called Dyson TP09 (600$) and expensive body creams to alleviate pain. Additionally I do swallow antihistamine tablets before sleeping - And everything without any success so far. But I still believe there must be a way to get rid of this pain. Never give up! :-D
