Thanks for the reply folks, yeah that all sounds like what it could be. My shabby diagnosis was something along the lines of my blocked sinuses are residual effects from my cold and as I climb the air expansion is causing the sinus to, instead of release the air, expand. Placing pressure on underlying nerves and what not. Plus during the climb I can feel the air try and shoot out in quick bursts while it makes like squeaking noises around my nose.
