I would try and drop that Sudafed... it is very vasoconstrictive, over time.

Cool is okay, COLD is not. Cool feels better because the nerves that sense it have a priority over heat sensors. So providing cool temps covers up the signals from the heat sensing nerves.

You might find Biofreeze very helpful... it has a gel with menthol that artificially gives the cold sensations without the temperature change and the affect on the blood vessels. It tricks the cold receptors therefore only and leaves your circulation unaffected and unconstricted.

You can now get it on Amazon and iherb.com instead of from chiros and PTs like the old days.
