Question: I have been having uncomfortable sensations in on the left and middle of my chest. I have been withdrawing from sugar/caffeine and am quite anxious. 3 nights ago my heart felt 'fatigued' when i was cycling, though i was pushing myself quite hard, and has not happened since at all when i exercise. This uncomfortableness doesn't seem to change during exercise in any noticable way. I do have a bit of a cough that comes and goes. I have been to a doctor, but had not been having these strange sensations, i would not call it pain, but it is uncomfortable anyway, it is chronic, and goes away for a short while occasionally, it is mild, perhaps a 2 out of 10, maybe less. I had an EKG done, all fine. Should i be worried that it is my heart?

Hi there, thank you for your response.

I think anxiety is a massive part of this, as i distract myself and i feel fine, i can imagine if it were serious i would notice it when i do not focus. My left arm feels slightly tired too now, especially raising it, perhaps i have hurt my pectoral muscle... i have no idea

i am obese(just) however, and lead a fairly horrible lifestyle, but that has changed now, perhaps i should have put that in medical history. Though i am exercising (a lot, and loving it). I hope that does not change it, hopefully my age would suggest i havn't had enough time to seriously damage my heart in a permanent way. This discomfort seems to be mostly in my heart area, which makes me worry that it might not be as you say, however it occasionally does feel like it comes from my middle chest area (though that has not happened for a while now). Like i said before, just to re-iterate, this doesn't feel like pain.. occasionally perhaps there is pain, for a split second, and a 1-10 kind of pain. I'm just re-writing this as this stresses me out soo much. I think the biggest reassurance for me is that exercising distracts me from this, and best of all does not seem to make my symptoms worse, which hopefully suggests it is just anxiety because of my experience when i was riding (which i pushed myself way too hard). It has been almost 10 days since i've stopped with any major sugar intake, i have stopped once before, and am not sure how long symptoms last, but i am definitely anxious regardless, i worry about my health a lot, and now that i've decided to diet and lead a healthy lifestyle it worries me so much more that i may have already caused myself irreversible damage.

I hope what i have written made sense, hard to think clearly in describing this when i'm anxious like this, but your response has been reassuring.
