Long term allergy problem?

my allergy's usually act up when the seasons change from winter to spring, but this is getting really anoying. I have been very congested since the beginning of summer.blowing out yellow mucus, headaches, tiredness,constantly sneezing my neck hurts and gets very stiff at times, and I dont have a cold. On top of that im now getting an ear infection. Ugh Its been going on way too long. Is there anything at home i can do for my ear infection? I remember being little and would get swimmers ear like crazy and i think my mom used peroxide. but im not quite sure. If anyone has any suggestions that would be most helpful. Im thinking about going to get a Neti Pot?
