Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of
musculoskeletal pain due to pulled muscle is more. But since it is left sided
chest pain, better to first rule out heart diseases.
So get done ecg first.
If ecg is normal then no need to worry for heart diseases.
Follow these steps for better symptomatic relief in musculoskeletal pain.
1. Avoid heavyweight lifting and strenuous exercise.
2. Avoid bad postures in sleep.
3. Avoid movements causing pain.
4. Take painkiller like
ibuprofen.
5. Apply warm water pad on affected areas.
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.
