Well buttercup...Sorry to HEAR you are plugged up.
You said..
"She looked in my ears (twice now) and could see pressure there, but nothing else."
Now... hmmmm... why doesn't that surprise me?
HA!
No brain, no stuffings, no NOTHING!
Got c'ya!
I'll bet that symptom feels like when you go up and down the mountain.. but the ears are "stuck" in one mode and won't fix themselves.
Am I close?
If not.. what DOES it feel like?
You don't think it is a delayed reaction from the squirrel falling on your head?
Might you be suffering from DRS now?
Dropping Rodent Syndrome?

OK.. I will TRY to behave.
If the doc didn't see anything.. then my guess it is nerve related possibly.
TOTALLY a guess.
Several things to try..
Warm heat on your jaws, face, neck... and even a light massage of the area may help.
Try to "work".. actually PULL or STRETCH.. the lower jaws GENTLY away from the upper jaw joints. NOT HARD.
You do this by putting both hands.. your palms actually... facing your face.. like you would be if sitting at a table and resting your jaw in your hands.
Then pull gently or stretch the muscles in your lower jaw.... and gently and slowly move your hands down toward the point of your chin stretching the skin and muscles.
This should take at least one minute to do.. cause you want to go SLOWLY.
Do it with your mouth closed.. then maybe again with your mouth open.. so different muscles are stretched.
This MIGHT give you some relief.. and it MIGHT not last long.. but at least you will know what the deal might be and how to fix it.
Then.. if that doesn't seem to help after stretching that area and wiggling your neck a bit..
Plan B
If the area is swollen... even if you can't see it.. the fluid may be pressing on nerves in the area. A kinda "squishy" thing going on in the tissues.
For that.. sudafed.. 12 hour non-drowsy for a couple of days helps me with that problem. Also a cup of dandelion tea to remove excess fluids. That may reduce the fluid enough to help?
If all that fails.. or only works temporary for you..
A chiropractor would be the next step. Chances are you MIGHT have slightly pinched nerves in your neck area .. perhaps due to the hacking and coughing.
They might use some light traction to stretch your neck muscles which by itself may relieve the problems.. UNLESS they put the traction strap UNDER your chin... so don't do that.. ok?
One more thing..
Have a friend stretch your neck muscles a little while you lay on the floor on your back.
Do this by placing a large towel under your fat head.. I mean skull.. and have them gently.. from a position on the floor behind your head.. and slowly pull the towel towards them. You may ned to hold the towel against your head with your hands so it won't slip. Have them stretch till you feel the stretch.. and hold it for 30-40 seconds or so.. and then SLOWLY .. VERY slowly... release it.
You MIGHT need to do this 2 times.. to get it right.
Just go SLOW...
OK?
If all else fails.. ice packs on the jaw area may work.
If heat don't.. sometimes ice or cold will.
Let us know if you get some relief.
Thinking about you...

WHAT?
What did she say? WHAT?
HA!
