Hey there Becky - all the best with the testing and trust you get some relief asap once done.
I haven't had testing done for years (I think I was about 11 or 12???) but my hayfever is always predictable and for years I ingested antihistimine tablets.

I did try a course of injections in the arm one year, and I also tried homeopathic alternatives - injections in the back and cream to rub on the face.

When pregnant I asked for a topical alternative and got eyedrops and nosesprays which occasionally needed "topping up" with tablets.

However, at 43years, I can safely say that I am "growing out of it". This season I have not needed to take any tablets, I have not had what I term as a "bad day" (where I don't venture outside at all). I am using nosespray and eyedrops, but I would say my biggest 'defence' against hayfever is sunglasses - I wear them all the time if outside - even if driving in the evening I wear non-dark glasses. Within about 15mins of not wearing my sunnies, I have itchy eyes and my nose is beginning to run.

Some days I forget to take my spray/drops, but wearing my sunnies all day means I have very little hayfever effects.

All the best... and to all of you with seasonal allergies, may you grow out of it soon
