welcome to HCM!
I have gone through your question and from that it is apparent that you are concerned about having pressure on your chest, you have gone through tests which are normal. You have asked - if it can be due to stress?
Well, from my clinical experience: I can say that feeling of pressure on chest, having breathing difficulty, or even having complaints of pain in chest--- can be due to stress or some acute psychological problem. We see such cases every day. But, one must rule out other things related to heart and other major organic condition before labelling it as stress.
As you have mentioned that tests are normal, which I suppose must have included an ECG and
x Ray chest, and may be an
ultra sound abdomen ( for
gall stones) , we can almost rule out the major illness which resemble by having similar symptoms.
###If you have some recent stress which correlate with appearance if these symptoms , then you must talk about it with someone close, and try to relax and solve it . If not, then please see a doctor, preffrably a
psychiatrist and get treatment.
Hope the reply is useful
