Stomach hurts and breathing feels slow and a cooling sensation and feeling weak. beginning of this week my upper left chest feels a lot bigger then my right (i dont know if that makes sense) and feeling discomfort in left breast. chest feels tight?

I recommend seeing your MD for evaluation. If your symptoms are more noticeable at rest rather than with exertion, I would ascribe them to anxiety& tension. If there's associated coughing, a respiratory tract disorder is more likely. Upper abdominal discomfort can be from gastritis. Your MD can advise you best after an examination & any appropriate testing.

One possible cause is asthma which may be triggered by environmental factors including smoke exposure. Chest wall inflammation or injury may also lead to pain which may be relieved by a heating pad and ibuprofen. Please see your physician and a virtual consult with Healthtap is available.
