Welcome in H.C.M.
I have gone through your query regarding your sore throat
which is resistant to the treatment you have taken till now.
You have so many antibiotic but no response thus possibilities in your throat are-
(1) Oropharyngeal candidiases.
(3) Tubercular pharyngitis
secondary to chest tuberculosis
To find out correct diagnoses and to differentiate above possibilities you should go for-
(1) X-Ray chest PA view.
(2) C /S of throat swab.
(3) Upper G.I.Endoscopy
(4) Blood- C.B.C.
In this way one may reach the final diagnosis which can be manage accordingly.
Hope your query is explained now
