It's now been more than three weeks I experience constant (each second of the night and day) shortness of breath. It progressively slipped into my existence in the form of recurring episodes that lasted a few hours, and become more and more frequent with each passing day. Coming along with it was almost constant post-nasal drip, and periodic cough phases (I get an itchy throat once in a few days when the night comes) as well as a stuffy nose (my sense of smell is not affected). I also originally had chest/jaw/shoulder/back 'stabbing' pain arising with it, and from time to time a burning sensation starting in my best and spreading in my limbs, but the pain/sensation tends to come and go and got greatly alleviated with time. I have been to the ER twice in a month because of this, and they obviously haven't found anything wrong with me. I have had two complete blood panel, two EKGs, further hormone and vitamin level testings, a lung X-ray, an abdominal X-ray, a thyroid ultrasound and everything was normal except: the urea and poly eosinophils levels (low), and my peak flow meter score (250). For the last one, the doctor explained it by the fact I seem to have "small lung" and not a lot of strength; indeed, I am a tiny 21 year old woman with my 5'6" - 90 lbs, and nobody can find the underlying cause of my skinniness (no, it's not anorexia) I always wake up with odd pain, yesterday I even woke up with sharp pain in both of my tibias and still have it. Now, what I would like to know is...what could explain this constant shortness of breath? Lung or cardiac problems (I haven't had further exams in these areas)? Allergies? Possibly (allergic) Asthma? GERD? Anxiety?
I have episodes during which the shortness of breath is even worst, I noticed that it's usually when my nose gets really stuffy, and my post-nasal drip is more abundant. I had something similar happening to me last summer for a month or so, but it was only periodic shortness of breath (not lasting more than an hour here and there) with practically no pain at all, but post-nasal drip as well, and nausea (which I haven't experienced in a while). It progressively disappeared at the end of the summer, and perhaps randomly came back a few times during the winter but always quickly went away, not lasting more than an hour. Only to come back episodically around mid-march, and it never left ever since.
