Pain.
There is a type of pain, where the pain is located adjacent to where the problem is. For example, if you have bronchitis, you may feel discomfort in your throat and chest but the back of your neck and shoulders is where it really aches.
I know there is a name for this but I can’t think of it and about a dozen searches with variations on that bring up LOTS of different results, I can’t seem to find it.
What is this phenomenon called?
Not a doc (and don’t play one on TV), but “referred pain”?
DING DING DING! Thats it, thanks Thelma, that was driving me nuts
I can now say I did one useful thing today. Thank you! 
How often have you coughed so hard that you threw out your back? You know, right between the shoulder blades?
I have never coughed that hard, personally. The worst I’ve ever suffered was a coughing jag that induced vomiting. I had pneumonia, well some sort of respiratory infection anyway, as a kid and my body was struggling mightily to clear the airways for easier breathing.
Done both, and there is also an adhesion on the right side [the sort of lower inside corner of my shoulder blade is the best way to describe the location on the outside, from a small blowout I had in that lung.] I can feel the adhesion get pissed off when I cough too much, or vomit a lot [yay for cancer and effectively 3 years of running nausea and vomiting - and I thought hyperemesis gravidarum was a bitch.
Ever vomited so much and hard that you blow out blood vessels in your eye from the blood pressure spike? I had to go to a seriously important business meeting looking like a movie vampire [or whatever monster it is that had red corneas.]
Dental pain can be a lot like this, apparently because of the way the nerves to the teeth are configured. One irritated tooth can give you neuralgia all sorts of places on your face or other teeth.
Ayup! I’ve had that, went to the dentist for a tooth ache, turned out I had a sinus infection
And I’ve had the opposite - sinus pain caused by an inflamed tooth nerve. People are built weird.
That’s every time I vomit.
I worked with a guy who got one of those mini-hemorrhages in his eye - from sneezing! It scared him enough that he saw his doctor, and the doctor said his BP was otherwise normal, and if it happened again, to see a cardiologist. You’re right, it looks dreadful.
I have not had the (dis)pleasure of heaving hard enough to cause a blood vessel to burst in my eye. Sounds horrible, based on how I generally feel after normal vomiting(body aches from the effort, etc)
Yup! I had a terrible toothache once and begged my dentist to squeeze me in. He said he’d try to see me in the afternoon, but asked me to take a Sudafed first.
I didn’t need to see him.
The one time I was hospitalized after presenting with localized extreme stomach pain, they were “99% certain” it was acute appendicitis because of the quadrant of my gut it was centered in. But nope, the problem was in my duodenum - as you can see nowhere near the appendix. That quadrant of my gut was basically pain free 
. Apparently referred pain relating to the abdomen is reasonably common.
Huh, that’s interesting. I guess I’ve never actually seen or paid enough attention to an illustration of the human digestive tract. I had no idea the stomach was that high up or far off to the side as that. Talk about referred sensation. When I eat until I feel full, where that stomach is shown is not where I feel full. The fullness sensation comes from basically where the jejunum is shown.
Learned something new today.
