Hello!
Thank you for asking on HCM!
I understand your concern and would like to explain that your complains seems to be mostly related to increased
stress and
anxiety, as it looks like a kind of palpitations, and nonspecific
chest discomfort.
There are several factors, why you experience such feelings, and the heart reacts that way.
Smoking, several stimulants like excessive alcoholic drinks, caffeinated drinks, general anxiety, etc may be accused many times to be the cause of those complains.
My advice is to perform a general routine check up to your GP, wit ha careful physical exam, and some additional lab tests, to rule out any possible body system disorders, and avoid all the above mentioned triggering factors, including Mountain Drew (it has a caffeinated version as well).
Hope to have been helpful to you. Greetings! Dr. Iliri
