Funny you should mention that only your left eye feels this way because I am having the same problem and only my right eye feels strange! This has been going on for me since the end of April and somedays it feels fine but much more often my right eye feels puffy on my upper eyelid and sometimes in the corner of my eye and nose. I have tried patanol and that does not help. I have never had allergies in the past so I really dont know if this is allergies or not. As far as runny noses my nose is not runny at all however I have been pretty congested off and on.

Do you feel any pressure when you press on your forehead?
Are you getting headaches?

I ask that because I have been getting headaches and if I press on my forehead the feeling will linger.

Hopefully this feeling will go away for you and I as it is very annoying!
