Thanks for your question on Health Care Magic.
I can understand your husband's situation and problem.
In my opinion, you should immediately take him to the hospital and get done chest
x ray.
He had blunt
chest trauma due to fall. He is also having worsening pain and breathlessness. So possibility of
rib fracture,
pneumothorax, Pulmonary contusions etc is more. And all these are seen after blunt chest trauma.
So chest x ray is needed to rule out all these.
If chest x ray is normal than no need to worry much for all these complications.
Ask him to take painkiller and
muscle relaxant drugs. Avoid movements causing pain. Avoid bad postures in sleep. Avoid strenuous exercise and heavyweight lifting. Apply warm water pad on affected areas.
He will improve in 1-2 weeks, but first get done chest x ray to rule out other complications.
Hope I have solved your query. Wishing good health to your husband. Thanks.
