Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
If the Xray has shown CP angle obliteration, you should undergo an ultrasound
of the thorax to confirm the presence of fluid there as the cause of opacity and it should be drained (tapped) with a needle under local anaesthesia and sent for lab to confirm infection or otherwise.
Infections (including TB), cancers and lot of other conditions can cause this.
But short duration of high fever
is more likely to be due to infection.
Did you have cough
, expectoration, breathlessness, blood in sputum, weight loss?
Needs to confirm by a good physical examination, labs, CT scan
if needed, tests for TB like sputum exam etc.
If you could detail up your symptoms, other tests, reports, Xray here on the site using the uploader available below the text box, I would be more than happy to help you precisely.
We should always give TB treatment only on confirmation. I advise you to be properly evaluated for the exact cause.
TB meds do cause side effects like jaundice
and some times serious.
I hope you are fully satisfied with the guidance I gave.
Hope I have answered all your questions. I would be glad to answer any further queries. Please ask for any clarifications before closing and rating this answer.
Thank you and Good luck!
