I'm 25, female, no allergies, no diagnosed illnesses, normal weight, and aside my symptoms, regular, good health.
For almost 2 years, I've had occasional palpitations (the feeling of skipped / extra beats, or then simply a few beats significantly stronger than others, usually in a very regular fashion, I mean that there is a regular rhythm to these when it happens - most of the time). It started as occasional, then daily, and would come and go in periods of weeks or even months.
Last spring it got worse: I got chest pains (all sorts, sharp and stabbing and in specific areas, as well as tingling / burning in larger, not entirely specific areas, as well as intense squeezing pain in the middle). I could move, go about my daily life etc, but it was seriously present, affected my sleep, my mood, got me scared etc. Every EKG turned out normal, bloodwork normal, and just this fall I had a stresstest and echo, both normal. The skipped beats were never present in EKG, but they're there - sometimes even every 5th beat or so, and can last several minutes, even hours. Then, sometimes weeks with nothing at all.
I feel fairly confident in saying I generally eat healthy. I exercise, although I do sit a lot. I do stretches and small exercises especially for the thoracic spine every day. Since then, most of the chest pains have gone away - but they come and go, mostly the ones associated with breathing, postures, and on specific spots on the chest, the pain being sharp or dull.
But now, since Oct, twice I've woken up with tachycardia. My heart felt pounding, it woke me from sleep. Bpm was first, I'd say, 140-150. It dropped to about 120 in a couple of minutes, stayed there for a while. Once the ambulance came (10-15 min), it was only 110 or so. It stayed around there for over an hour. EKG normal (sinus tachycardia). On the second time, the episode lasted a bit less, and bpm was lower, and it felt less pounding (I had been exercising more regularly ever since the 1st episode), yet it woke me from sleep and was still over 120 when waking up. It clearly felt like my heart had some "malfunction", by that I mean it wasn't the same sensation as when your HR elevates because of exercise, getting scared / angry etc. And my rest HR is usually 50-60, even below 50 when lying down.
Sometimes I also feel vibration in my chest, numbness in left index finger / big toe, or tingling in armpits.
Generally, pulse feels normal, but there is both normal variation (e.g. with breathing) as well as a skipped or extra beat (or two) every now and then - I don't know if it's still regular enough to be considered normal. My HR monitor sometimes gives the icon for arrhytmia.
I also often feel numbness right above my left breast, or slight pain / tingling / numbness in my jaw or left side of my neck. Sometimes my sense of touch feels heightened, e.g. just the blanket touching my neck while lying in bed may feel as if something's wrapped more tightly around it, or a part of clothing touching my chest feels like something's pushing. It's not painful, but it feels unusually "strong".
Sometimes I feel as if I am unable to inhale enough air, but only slightly, and this does not happen to often anymore. Also, often I feel as if my heart is beating fast or very erratically, but when feeling the pulse from my wrist, it seems slower and steady.
This is really disturbing my life. It has been going on for months, and I still don't know what it is. I've come a long way in not freaking about it, but it still does unnerve me, and happens even when I'm calm, thinking about something else etc. and I find it extremely difficult to just believe "it's normal" - I do not feel normal.
Please, is there anything concrete to explain this, can I do something about it?
Is it heart, is it sleep apnea, MS, my imagination?
Anyone else having all this?
Sorry for the lengthy post...
