Heart related issue. I go to gym tho?

Hi I am 26 year old , I have chest pain in left side under the left breast, In the shoulder and both earlobes , I always suffer from panic attacks , I am taking nexito plus as prescribed too , Are these the signs of heartattack? Today I have severe pain in ear especially in my left ear ? My jaw and there is a light pain in my head with parched throat. Today I had an episode of pannic attack too, I am concerned and worried about all this , is my body giving me some kind of signals related to my heart health , Because there are many many episodes where my heart rate have gone high all of a sudden , I am a overthinker , A short tempered person and have a stressfull relationship where I have these panic attacks often i feel today i am having sharp heart pain and a symptom of heart attack maybe!?? i go to gym tho ? I work out 4 time a week most probably lifting moderate weight and today my partner had creates a situation where I had these mini panic attack with anger , im ex smoker too.
