Thanks for your question on Health Care Magic.
I can understand your concern.
Since your
chest pain is associated with movements (bending), possibility of
musculoskeletal pain is more.
But better to get done PFT (Pulmonary Function Test) to rule out
bronchitis because you are having breathing difficulty too.
If PFT is normal then no need to worry much.
Musculoskeletal pain is more likely.
So avoid movements causing pain.
Avoid heavyweight lifting and strenuous exercise.
Avoid bad postures in sleep.
Start painkiller and
muscle relaxant drugs.
Apply warm water pad on affected areas.
Don't worry, you will be alright.
Hope I have solved your query.
Wish you good health. Thanks.
