Thanks for your question on Healthcare Magic.
I can understand your concern.
Possibility of
musculoskeletal pain is more but better to rule out heart diseases first because left chest paid and left hand discomfort are commonly seen with heart diseases.
So get done ecg and 2d echo.
If both these are normal then no need to worry for heart diseases.
Musculoskeletal pain due to long work out is more likely in your case.
So follow these steps for better symptomatic relief.
1. Avoid heavyweight lifting and strenuous exercise.
2. Avoid movements causing pain.
3. Avoid bad postures in sleep.
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.
