Dear thanks for the question.
You should have mentioned about treatment taken too, as a course of antibiotics would have cured him. In that case a course of
levofloxacin 500mg for 5 days can be tried before moving further .However if i were your treating doctor I would have followed following
1 blood work up for infections, level of
haemoglobin, platlet count
2
sputum culture and sensitivity for antibiotics.
3 sputum AFB test to rule out
tuberculosis as you have history of travel.
4 there is a possibility of malaria too if history of mosquito bite is there.
5
ultrasound scan of abdomen
6 nutritious diet with increased proteins and vitamins.
Your treatment can be decided based on investigations report only as you have
chronic cough, fever, tiredness. Left side
chest pain can be due to lung(tuberculosis), heart (infection, MI), spleen (malaria).
You can request above steps from your doctor and start treatment. Don't delay it.
I hope my reply will benefit you. Please write for follow up queries. Kindly rate this reply. I wish your husband a rapid recovery. Thanks
