Thanks for your question on Health Care Magic. I can understand your concern. You had blunt chest trauma 1 year back. Even if you have fractured rib, by the time it must have healed. But healing might not be proper because you have not taken proper treatment for this. So possibility of malunion (inappropriate healing) of fractured rib is more in your case. So in my opinion, you should get done chest x ray to rule out this. Treatment is conservative only. Wear rib belt to avoid mobilisation of segments. This will improve healing in alignment. Avoid movements causing pain. Apply warm water pad on affected site. All these will give you symptomatic relief. Hope I have solved your query. Wish you good health. Thanks.
