The symptoms can vary from person to person. Mine change each year.
This year, I am sneezing a lot, have itchy ears, itchy skin and a dripping nose. Charming, isn't it!
Last year I suffered with itchy eyes, which became rather red and sore, resulting in feeling tired most of the time, stuffy nose and a crappie cough. A bit like a summer cold, but all season!
The last time I had really bad hay fever I used local honey - I was sceptical but it worked (and it was a lot cheaper than tablets). Haven't had it since.
Yes, you can buy the anti histamine drops over the counter although they didn`t work for me. There are a few products around (sodium cromoglicate 2% is another one) and you hve to find what works best for you.
No common or garden and run of the mill hay fever for me. After a visit to the opticians they have diagnosed Blepharitis. Lots of drops to put in my eyes:-(
