Thanks for writing to Healthcare magic,
I have studied your case,
5 months is sufficient time so that symptoms are reduced or painfree state is achieved.
Now you should investigate for nerve
entrapment due to fracture
You can do MRI or HRCT
for pattern of injury
till time use rib belt or chest support, local analgesics.
If whole of left side body is swollen then MRI brain is advised.
Hope I have answered your query. Let me know if I can assist you further.
