Well, when we feel lousy much of the time....we get into a hypersensed state. Like the princess and the pea syndrome!!
It's possible you've been exposed to a virus and your tonsil's are working overtime.
Your ears itching - wow, I can relate. I use a q-tip dipped in peroxide (the stuff for cuts) and wipe it around in the outer ear canal...that helps a lot.
Also, you could do a nasal wash with warm water and salt and what I've read lately..add a bit of baking soda. That will also help with the itchy ears and plugged feeling.
Sudafed (oral decongestant) is another option to open the passages and eustachian tubes.
As well, gargle with salt water..that helps shrink some of the swollen tissue in your throat.
Drink lots of fluids, take your vitamins, get enough sleep and if you do end up with a cold...at least you'll know what the cause was
Maybe you could eventually make an appointment with your dentist and consider getting the wisdom teeth out. Especially since it's changed the alignment of your jaw. That could ultimately set you up for future mandibular joint problems.
Like I mentioned earlier, I'm just getting over a cold. It started much like how your symptoms are, but with severe pain around the ear and into it when touched. I still have the throat feeling and it's quite severe. I have asthma as well, and had to increase all my meds...but it just seems to be the nature of this virus -- that darned throat feeling. I'm hoping to feel better soon!!!!!
and the only thing I seem to be focussing on is this burning pain in my throat (larynx).
Let me know how it goes.
