Is this an allergy or a cold?

as far as I know I'm not allergic to anything, but over the years I've developed sensitivity to different foods like pineapple. basically what I have is a sore throat, clogged ears, a kind of achy chest area (my lungs I think) and a slightly runny nose. other then that I feel fine, I have my appetite, I'm a little tired but I dunno if that's relevant. I was golfing on monday and there was a lot of pollen on my car when I got back and I noticed on tuesday morning that the back of my throat was sore. so what is it more likely? a cold or allergies?
