Thanks for your question on Health Care Magic.
I can understand your concern.
Possibility of lower
respiratory tract infection (LRTI - pneumonia) is more in your friend's case.
Yes, cold weather must have contributed to her current illness.
She is also a cancer survivor and took
chemotherapy and radiotherapy. This makes her immunocompromised and more prone for infection. Her symptoms like fever,
chest pain, breathing difficulty etc favour pneumonia more.
So better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. Chest x ray
3.
Sputum culture and sensitivity report.
Chest x ray is must for the diagnosis of pneumonia.
Sputum culture will isolate the causative organism and sensitivity report will guide about effective antibiotic treatment.
Don't worry she will be alright.
Consult pulmonologist and discuss all these.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your friend. Thanks.
