Thanks for your question on Health Care Magic.
I can understand your concern.
No need to worry much if your chest
x ray is normal.
You are having blunt
chest trauma and this can cause rib
fractures,
pneumothorax, lung confusions etc. Chest x ray is needed to rule out all these. Since your chest x ray normal, no need to worry for these complications.
You are having simple
musculoskeletal pain and swelling due to inflammation.
This will resolve in 1 week with following measures.
1. Avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain.
2. Avoid bad postures in sleep. Apply warm water pad on affected areas.
3. Take painkiller and anti inflammatory drugs.
Don't worry, you will be alright and swelling, pain will subside.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
