breathlessness, shortness of breath, chest pain and tightness,
heart palpitations (fluttering, pounding, irregular heartbeat), dizziness, fainting spells and tremors mainly in my hands.
I can't even go up the stairs normally, or even run 5-10 metres to catch the bus, I feel like my lungs are collapsed and can't breath, I have really bad chest pains and heart palpitations.
