If your throat is tickling--scratch your ear (Scott Schaffer, MD, ear nose and throat doc in NJ). The ear and throat are connected--you can create a throat spasm that stops the tickle.
To hear better, use your right ear for listening to people talk, and the left for soft music tones.
If you need to "go," think of sex--this is a good distraction for a full bladder.
Sinus congestion? Thrust your tongue against the roof of your mouth, then press between your eyebrows with one finger. In 20 secs, your sinuses will begin to drain. Something about the vomer bone--I don't know what that is.
Sleep on your left side for less acid reflux.
If you get a minor burn, cover it with your fingers not ice or cold water--less blistering.
For a nosebleed, put some cotton behind your upper lip and press. Most bleeds come from the septum and this stops them.
