I Have Been Experiencing A Progression Of Symptoms Over The

I have been experiencing a progression of symptoms over the past 6 weeks or so, starting with an ear ache in my left ear. It was dull and persistent, but I carried on. Perhaps 1-2 weeks later I experienced what felt like pinkeye, but there weren't any visible signs -- just some really severe itchiness. That resolved after about a week and then a nasal condition started with a mild-to-moderate sore throat. That evolved into some gastrointestinal discomfort and one weekend of diarrhea (about 7 days ago). The earache has persisted throughout. Four nights ago, I developed a headache on the top of my head. I have had migraines or cluster headaches before, it was definitely not that and was definitely not a sinus headache. It was a generalized "fire" on the top of my head. Some unknown time later, I noticed what feels like a dent in the top of my skull, from the front center edge of my hairline back about 5 finger-widths. Sometimes it is tender, sometimes it is not. The next day, I went in to my doctor and talked through as much of this as I could remember. They called for blood and urine workups, a full abdominal ultrasound, and a 2-view chest x-ray to start. All of these tests came back in normal ranges except for the chest x-ray: Emphysematous changes of lungs noted with hyperlucency, increased interstitial markings, and flattening of the diaphragms. No evidence of consolidation and pneumonia seen. The pleural reflections appear normal. No pleural effusion is present. Cardiac size and contour are normal. Thoracic aorta normal. No hilar or mediastinal enlargement. Osseous structures are normal for age. That was 3 days ago. About 24 hours after receiving that information, I started feeling shortness of breath that comes and goes but is unrelated to physical exertion. I can walk up and down a hill for half an hour no problem, just like I could a week ago, but if I'm sitting still in a car or on a chair things start to get weird. I am still feeling an occasional sensitivity on the skull ridge as well. My question: what should I do next? I wouldn't be surprised if anxiety about a possible emphysema diagnosis was causing some stress, but that doesn't speak to all of the other random symptoms. They all seem unrelated, if not for the fact that they're all happening around the same time.
