I assume that you have fractured ribs, which was not properly reviewed and treated.
X-Ray will clearly reveal how many ribs are fractured and their displacement.
Antibiotic, anti inflammatory pain killers and local application of pain killing gel, application of ice and hot water fomentation and rest to that area by compression bandage are the treatment.
Correct approximation of the fractured site is not needed.
As you say 3 months are over after the injury
– Take a Check X-Ray to analyze the fractured ribs and plan for further management. Usually surgery is not needed. Regarding the duration of rest what games to be avoided – discuss with your doctor. Why frustration for this.
