Welcome in H.C.M. for consultation.
I read your query regarding dry cough
and blood on spitting of your mother. You have consulted your family physician who advice X-Ray chest for her, but she avoided for X-Ray due to financial crises.
Considering these facts I would like to tell you that your mother may develop so many complications if remain undiagnosed and untreated, so please convince her for -
(1) X-Ray chest PA view
(2) Culture and sensitivity of throat swab.
(3) Sputum for Afb.
After these investigations one can diagnose her disease and plan for treatment.
