Coughed really hard and started to have intense pain under the chin on the left side of my neck. Coughed again and the back of my head feels like it s exploded. Had crippling, stabbing pain that forced me to the floor for about five minutes. Now, it s incredibly tender to the touch and aches badly. Ears are ringing and I feel slightly slurred with popping lights in my vision. What happened and what should I do?
Yeah, hard to say. It isn't that common to have a (minor) punctured lung do this with coughing. Generally we like to put someone in the hospital 24 hrs with this to make sure the puncture heals itself (ok, it ALWAYS does, but its pretty Chat Doctor.  This isn't that rare. Can be an irritated structure of the neck/respiratory tract. This isn't rare, this isn't serious. It mostly doesn't show up on exam or x-ray or even MRI. Only does if there is a (minor, but treatable) sinus infection or ear infection along with it. So, there's several things, there is a 1 in 20,000 risk of dying from an untreated sinus infection. A much, much higher risk of having permanent hearing decrease from an untreated ear infection and mostly this gets better on its own but does a lot better and faster with treatment.
