Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, possibility of
musculoskeletal pain is more but since it is left sided
chest pain, we should first rule out heart diseases.
So get done ecg, 2d echo and
stress test.
If all these are normal then no need to worry for heart diseases.
Apply warm water pad on affected areas. Avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise.
Avoid sudden jerky movements.
Take simple painkiller like
paracetamol or
ibuprofen.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
