Thanks for your question on Healthcare Magic.
I can understand your concern.
You had blunt
chest trauma due to fighting and the cracking sound is mostly due to
rib fracture.
So better to get done chest
x ray for the diagnosis of rib fracture.
Follow these steps for better symptomatic relief in such cases.
1. Avoid movements causing pain.
2. Avoid bad postures in sleep.
3. Avoid heavyweight lifting and strenuous exercise.
4. Apply warm water pad and ice pack application on affected areas.
5. Take painkiller and anti inflammatory drugs.
6. Sit with proper back and chest support.
Don't worry, you will be alright with all these in 1-2 weeks.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
