Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you are mostly having
musculoskeletal pain due to heavyweight lifting.
But since it is left sided
chest pain, better to first rule out heart diseases.
So get done ecg and 2d echo first.
If both these th are normal then no need to worry for heart diseases.
Follow these steps for better symptomatic relief in musculoskeletal pain.
Avoid heavyweight lifting and strenuous exercise.
Avoid movements causing pain. Avoid bad postures in sleep.
Apply warm water pad on affected areas.
Take painkiller like
ibuprofen.
Don't worry, you will be alright with all these in 2-3 days.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
