First thing is not to worry ..
U have completed treatment for tb means it is cured ..
What I get from ur history is u had simple respiratory tract infection which is common in patients who had tb..
Or it could be anything else too ..
Worrying ll not solve the problem..
U took the first line antibiotics, but didn't help ..so better to evaluate
Get CBC , Esr, Typhoid serology , malarial serolgy and urine routine and microscopy ..
Next Steps
get these blood t3sts done and get back to me if u wanna consult ..
Health Tips
just take paracetamol/ Dolo 650mg tablet for fever ..
don't take anything cold
