Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
The fall your husband had might cause
injury to bones underneath (ribs or vertebra), a strong hit can cause trauma to
soft tissue (causing inflammation and probable blood collection), important organs like liver or
kidney may get injured and need early treatment.
Looking at his age, I would advise a visit to ER and get examined by a doctor and
first aid treatment as per need. Get investigated as per doctor's suggestions. In my view, MRI would be better investigation to give better picture at the site of swelling.
Before transferring to ER he should take rest lying on the left side. Let him take sips of juice or water or water to keep energy level normal. Ice bag will soothe a bit. Do not
massage or foment.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Vasudha Jayant Athavale
