Thanks for your question on Health Care Magic.
I can understand your concern.
Possibility of post traumatic
costochondritis is more in your case.
Costochondritis is in of rib
cartilage. It is common after
injury.
ESR (
erythrocyte sedimentation rate) is raised in inflammatory conditions.
So this also favours costochondritis.
For better symptomatic relief follow these steps.
1. Avoid heavyweight lifting and strenuous exercise.
2. Avoid bad postures in sleep. Avoid movements causing pain.
3. Start painkiller and anti inflammatory drugs.
4. Apply warm water pad on affected site.
5. Wear chest belt to prevent mobilisation of painful areas.
Don't worry, you will be alright in 1-2 weeks.
Hope I have solved your query.
I will be happy to help you further. Wish you good health. Thanks.
