Hi there,
For about a month now ive been experiencing various symptoms. Mostly everyday im uncomfortably short of breath, especially after even the slightest activity. Along with this ive noticed ive been having palpitations, one night i could suddenly hear my heartbeat pounding in my ears and it was beating very irregular. It felt like it was making 2 beats in quick succession, a kind of "flip flopping" feeling. I do not consume caffeine and i was in bed at the time. I get fatigued easily and i seem to be running a low grade fever.

When i exhale ive noticed im wheezing constantly.
Although i have asthma its mild and im medicated for it. The wheezing and shortness of breath dont respond to my asthma medicine but i really dont think this is whats causing my symptoms. My Doctor tells me people with asthma dont have a constant wheeze and that something must trigger it. My wheeze is consistent and always present even when im not feeling short of breath.

Ive also been having strange episodes where il inhale then il feel a pressure build up in my heart and it will beat once, very hard accompanied by dizziness and pressure in my chest and tachycardia.
All these symptoms are amplified greatly by exercise and im usually left unable to catch my breath with heart palpitations hours after any exercise.
Im worried i have a heart valve disorder or something like myocarditis.

Im a 19 yr old male, 5ft 8, 144lbs non-smoker non-drinker.

Thanks in advance for your time and help.
