Next day doctor started giving her New medicine after LP reportR-Cinex 450Pyzina 500Combutol 800Ofloxacin 400 All schedule H drugs(steroids)Two days she had some relief in her pain today again she started complaining severe headache.If any doctor can give some advice it will be a great help.
If it is CNS tuberculosis then continue with medications prescribed. They are in adequate doses. Ofloxacin can be withheld. Please mention detailed MRI (preferably contrast) findings to comment better. Also go for CSF TB PCR and protein level in CSF, chest X-ray, man tour test.  CSF picture in this case is not classical of Tuberculosis Hope my answer will help you.  Take care.  Don't forget to rate me.
