I suffer from hay fever but I'm also allergic mould and bad dust. I have one antihistamine a day and I'm fine.
This has changed in the last month I am suddenly waking up with really bad allergies! Sore itchy puffy eyes streaming nose itchy throat and abit chesty.
Just to add. My mattress is under a year old with a mattress topper on top with a removable cover, I wash that once a week and hoover the mattress weekly also, I usually wash my pillows once every month but I've recently binned them and brought new ones at the weekend! I dust my room once a week.
Just wondering if anybody knows why this could be happening?
