Brief Answer:
Hot and cold compresses + pain medication...

Detailed Answer:
Hi,

The described symptoms are consistent with chest wall injury. Sometimes the strained chest wall muscles and tissues especially when severe take time to heal. Occasionally there could be bleeding into muscle and soft tissues that take time to resolve. Besides these two, a grievous fall can crack a few ribs and it could be painful with delayed healing.

It would be extremely difficult to predict which of the following is the cause here. A detailed clinical examination, X-ray of the chest and if needed an ultrasound scan is essential to identify the problem. I will encourage you to visit a doctor to get the tests done.

In the meanwhile, you should use heat (moist heat) alternating with cold compresses alternatively on the affected area. This should ease some of the discomfort along with pain medications you take. Avoid strenuous physical exercise including bending and lifting over. Cough may aggravate pain; so take precautions. Further treatment is based on examination and test results.

Hope this helps. Let me know if you need clarifications.

Regards
