Hello dear, thanks for your question on HCM.
I can understand your situation and problem.
You are having blunt
chest trauma due to fall.
And following are the complications of blunt chest trauma.
1. Rib fracture
2. Pulmonary contusions
3. Pneumothorax
4. Muscle
injury.
And in all of the above sever pain on movement is seen.
So better to get done chest
x ray to rule out all these causes.
If chest x ray is normal then no need to worry much.
Muscular injury is more likely in your case.
Try to follow these steps for better symptomatic relief.
1. Avoid heavyweight lifting.
2. Avoid strenuous exercise.
3. Avoid bad posture and movements in sleep.
4. Start painkiller and
muscle relaxant.
5. Apply warm water pad on affected site.
So rib fracture is less likely but can be the cause. So get done chest x ray to rule out rib fracture.
