What should you know about exercise for chest tightness?

Tightness may come from narrowed airways in Asthma or COPD, irritation from Acid Reflux, chest-wall muscle strain, or a surge of fear during Panic Disorder or Generalised Anxiety Disorder. Angina is a heart condition that commonly presents with pressure or tightness brought on by exertion. Chest tightness itself does not tell you which explanation applies. Note whether it starts at rest or with effort, how long it lasts, and whether it spreads to the arm, jaw, back, or shoulder.

Stop, sit upright, loosen restrictive clothing, and avoid restarting until symptoms have fully settled and you have medical guidance when needed. Follow your prescribed asthma or heart-care plan; use Inhaler Therapy only as directed. Do not exercise alone while a new symptom is being assessed. Arrange a clinical review before returning to strenuous activity if this has happened more than once, limits your pace, or is accompanied by cough, wheeze, palpitations, or reduced stamina.

Call emergency services for severe or persistent tightness, crushing pressure, major breathlessness, fainting, sweating, nausea, confusion, or pain spreading beyond the chest. Seek prompt assessment for a first episode, symptoms that recur with exertion, or discomfort that does not improve with rest. Do not drive yourself if you feel seriously unwell.

Could this be related to my heart, lungs, reflux, or anxiety? What activity is suitable while I wait for assessment? Should I have an ECG, breathing review, or medication check?
