Thanks for your question on Healthcare Magic.
I can understand your concern.
Your chest symptoms are mostly
costochondritis.
It is inflammation of ribs android
cartilage.
It is not due to trapped nerves. It is also due to carrying your baby.
So follow these steps for better symptomatic relief.
1. Avoid heavyweight lifting and strenuous exercise.
2. Avoid forward bending and sudden jerky movements of chest.
3. Apply warm water pad on affected areas of chest.
4. Sit with proper back support.
5. Take simple painkiller and anti inflammatory drugs like
ibuprofen or
acetaminophen.
6. Wear rib belt to prevent mobilization.
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.
