Hi Suza.g
I am not a medical person, but am a hayfever sufferer. Due to the way our weather has been, you may still be suffering from hayfever. I suppose you are taking anti histamines?
Sometimes, you may also find that you become allergic to something else over time. I, for example started with just grass pollen - but now I start in very early spring with tree pollen and finish with mould and fungus spores. - So nearly for the whole of the year.
Thank goodness for anti histamises.
Hugs
