Thanks for your question on Health Care Magic.
I can understand your concern.
Intermittent, dull aching
chest pain should be first evaluated for cardiac diseases.
So better to get done ecg and 2d echo.
If both are normal than no need to worry much.
Your chest pain is associated with movements.
So
musculoskeletal pain is likely.
So avoid movements causing pain.
Avoid heavyweight lifting and strenuous exercise.
Avoid bad postures in sleep.
Take painkiller and
muscle relaxant drugs.
Apply warm water pad on affected areas.
Don't worry, you will be alright.
But first rule out heart diseases.
Hope I have solved your query.
Wish you good health. Thanks.
