Hello and welcome to HCM.
Thank you for your query.
This pain is most probably due to pressure or tension of the muscles or ligaments of the rib cage
that were injured during your fall. If your chest x-ray has ruled out any skeletal injury
, it is not a matter of concern.
The muscular injury should take about 3-7 days to subside. In the meantime do not stress
or strain yourself, rest is advised, and possibly a topical pain management ointment (eg. diclofenac
sodium). If pain lasts for 7-10 days, you could visit your doctor to rule out any other possibilities.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
